How to Spot Fake Black Friday Deals on Certified Pre-Owned Tech

A pre-owned iPhone tagged "52% off" looks like the best Black Friday deal you'll see all week. Before you tap buy, ask one question: 52% off what? On refurbished and pre-owned tech, that answer is harder to pin down than it is for a new TV, because there's no single list price to check against.

Here's how to spot fake Black Friday deals on any device: ignore the percentage and check three prices. The "was" price the tag claims, the price the item has actually sold for over the past few months, and the price of the same device elsewhere today. On pre-owned tech, also match storage, condition grade, battery health, unlocked status and warranty. Mark the dates: Black Friday is the day after Thanksgiving, which puts it on Friday, Nov. 27, 2026, with Cyber Monday the following Monday, Nov. 30.

The "Was" Price: What Is It Really Comparing To?

A "was" price is a fair yardstick only if the item really sold at that price for a real stretch of time. The FTC's Guides Against Deceptive Pricing set out that test: a former price counts when it was offered to the public on a regular basis, for a reasonably substantial period, in good faith. A price inflated just so the "reduction" looks big is the kind of comparison the Guides call deceptive.

On pre-owned devices, the "was" figure is usually built from the maker's price, an earlier listing or a comparable new item, not from what that unit ever sold for in that condition. A pre-owned iPhone can also be measured against its launch price, long after the new model's own price came down, which makes the percentage look bigger than the saving.

It's like a hotel offering "40% off" its posted rack rate: unless you know what rooms there usually go for, the discount tells you very little about whether tonight's room is cheap.

Here's a worked example with made-up numbers. A listing reads "was $799, now $399." If $799 was the launch price, and the same model, storage and grade sells for $380 to $420 at three other stores this week, your real saving is close to zero.

This means a percentage off retail, at any store, Plug included, tells you the distance from a reference price. The next two checks tell you whether the price itself is good.

Price History: Look Back Months, Not Days

A real discount shows up as a dip below the price an item has held for months, so look back at least to September. Retailers are expected to stretch Black Friday into a longer "Black November" this year, with some deals online from late October. A price history that only covers the last week proves nothing.

Which?, the UK consumer group, has the research to show why. It tracked 175 products at UK retailers and found that 83% were cheaper or the same price at least once outside the Black Friday sales window (results published November 2025). In one Which? example, a robot vacuum sold for £299 in May and June 2024, climbed as high as £500 in October, then dropped to £350 for Black Friday. That "sale" price was £51 more than the spring price. The data comes from UK stores, so U.S. consumers should read it as a warning sign, not a local figure.

Here is how to check a price's past before you buy:

• Use a price tracker for Amazon listings: Free tools track an item's price over time, and some chart new, third-party and pre-owned offers separately.
• Check Google Shopping: Where Google has matched the product, its price insights say whether today's price is low, typical or high, and how it moved in recent months. You can also turn on price tracking to get an alert when the price changes.
• Look for six months or more: A dip that only appears after a September or October rise isn't a bargain.

Plug hasn't tested these tools hands-on, and no tracker covers every pre-owned listing. If a listing has no history at all, compare the same model, storage and grade at three sellers today, and write down each total. That snapshot is your price history.

Same Device, Same Grade: Compare Like for Like

A pre-owned price only means something next to the same model, storage, carrier status, grade and battery health. Change one of those and you're getting a different product at a different price.

Match these before you compare prices:

• Storage: A 128GB and a 256GB iPhone of the same model are different items, with different prices.
• Unlocked or carrier-locked: A locked phone can look cheaper because it only works with one carrier. Every Plug Certified phone is unlocked and works with any carrier.
• Condition grade: Grades describe looks, and each seller names and defines them differently.
• Battery health: The percentage tells you how much of the original capacity is left.

How grades line up, from each seller's published pages:

So a "Good" at one store and a "Good" at another aren't automatically the same phone, and our guide to certified pre-owned versus refurbished explains the wider labels. On that marketplace, Good means light micro-scratches you can't see from 20 inches away; Excellent, from 8 inches. At Plug, a Good, Great or Excellent device passes the same 90+ Point Inspection and carries the same 12-Month Plug Warranty; the grade is about how it looks.

Battery health is where pre-owned prices hide the most value. Apple says iPhone 14 models and earlier are designed to keep 80% of their original capacity at 500 complete charge cycles, and iPhone 15 models and later at 1,000, under ideal conditions (Apple Support, checked October 2026). This means two phones at the same price aren't the same deal if one shows 81% Maximum Capacity and the other shows 95%.

Ask the seller for the figure, or check it yourself when the phone arrives. The path differs by model:

• iPhone 15 and later: Settings > Battery > Battery Health
• iPhone 11 to iPhone 14: Settings > Battery > Battery Health & Charging

Total Cost: Warranty, Returns and Shipping Count as Price

The cheapest tag isn't always the least you'll spend once you add what comes with it. A phone with a short warranty and a phone with a longer one aren't the same buy, even when the number on the tag is the same.

Add these to the price you're comparing:

• Warranty length and what it covers: Plug's 12-Month Warranty covers hardware and software faults under normal use. It doesn't cover accidental damage.
• Returns: Check the window and whether a return carries a fee, and read up on the Black Friday return policy for electronics. Plug offers 30-day returns.
• Shipping: A low price with a delivery charge on top can end up level with a higher one that ships free. Plug offers free shipping on US orders.

Check the Seller, Not Just the Price

A deep discount on a site you don't know deserves a second look. The FTC warns that bogus shopping sites copy real companies' logos and product photos, then use unusually low prices to pull shoppers in.

Before you pay, run these checks:

• Pay by credit card: The FTC notes that disputes are easier with a credit card.
• Walk away from odd payment requests: Only scammers insist on gift cards, crypto, a wire transfer or a payment app.
• Read reviews from several places: Not just the seller's own site.
• Report a fake: If you hit one, report it at ReportFraud.ftc.gov.

Your 60-Second Checklist Before You Buy

Here is how to run the whole test before buying, in the order that saves the most time:

• Find the reference: Work out what the "was" price is: launch price, new price, or a real recent price for this exact device.
• Check the history: Look back to at least September, on a tracker or Google Shopping.
• Get three quotes: Same model, storage, grade and carrier status, from three sellers today.
• Read the battery figure: Maximum Capacity, not just a grade label.
• Add the extras: Warranty months, return fees and shipping, on top of each price.
• Vet the seller: Real business, real reviews, paid by credit card.

If you only have time for one check, make it the item's own price history next to the same grade elsewhere. A price that holds up against both is a real discount, whatever the percentage says. You can run the same test on Plug's Black Friday tech deals: every Plug Certified phone is unlocked, has battery health of 80% or higher, and carries the 12-Month Plug Warranty.

Frequently Asked Questions

Are Black Friday deals even real?

Some are. An earlier Which? study of 227 products at eight UK retailers found 90% were cheaper or the same price at another point in the year. One hairdryer "reduced from £49.99" hadn't sold at that price at that retailer in the previous 12 months. These are UK findings.

Are fake discounts illegal?

Yes, they can be. The FTC's pricing guides are guidance rather than a standalone law; enforcement comes through the FTC Act and state consumer-protection laws. That route doesn't promise you a refund. If you think a "was" price was invented, a screenshot of the listing and its price is worth keeping before it changes.

How can you tell if a website is fake or sells fake products?

Type the store's address yourself instead of clicking an ad. Look for a real business name, a way to contact a person, and return terms in writing. Compare the price with the manufacturer's own store. A very new website domain is another hint, though not proof on its own.

Do pre-owned tech prices drop on Black Friday?

Sometimes, and mostly on specific models, depending on stock, rather than across the board. Apple's own Certified Refurbished store advertises savings of up to 15%. Cyber Monday pricing tends to carry Black Friday's forward rather than beat it. For one device in particular, see how much iPhones drop on Black Friday.
