How to Know If You're Getting a Good Deal (When Everything's Marketed as One)
Every price online claims to be a discount. Most aren't. Here's how to figure out the real value of what's in front of you, fast.
The page says 40% off. The strikethrough price next to the current price suggests you're saving real money. The countdown timer says the sale ends in three hours. You feel the urgency. You also feel a low hum of suspicion — something about every product on the entire site being on sale at all times has started to ring hollow. But you don't have time to investigate, so you either buy it on faith or close the tab and feel vaguely defeated.
Most 'deals' aren't deals — they're a marketing convention. The strikethrough price is often the manufacturer's suggested price, which the product has never actually sold for. The 'limited time offer' resets every Tuesday. Knowing whether something is actually a good deal isn't about trusting the seller; it's about checking three or four things they don't want you checking. Here's how.
Check the price history, not the current 'discount'
Tools like CamelCamelCamel (for Amazon) or Honey/Keepa show the actual price history of a product over time. If today's 'sale' price matches what the item has cost most of the year, the discount is theatrical. If today's price is genuinely lower than its 60-day average, the deal is real. Five seconds of looking up price history beats 30 minutes of agonizing over whether to buy.
Compare across at least two unrelated retailers
Don't just check the price on one site. Look at the same product on at least one other retailer — ideally a less promotion-heavy one. The single retailer's 'discount' is meaningless without context. If three retailers all sell the item for similar prices and the one you're on claims a 50% discount, the discount is fake. If the price on your site is genuinely lower than on three competitors, it's probably real.
Watch for 'always on sale' patterns
Some retailers and brands run their entire business with everything 'on sale' all the time. Wayfair, Kohl's, many cosmetic brands, almost any DTC mattress company. The list price is fictional; the sale price is the real price. For these sellers, the question isn't 'is this on sale?' but 'is this priced reasonably for what it is?' Treat the discount as scenery, not a signal.
Calculate the unit cost, not just the total
For consumables — paper towels, coffee, contact lens solution, anything you'll buy repeatedly — the only number that matters is cost per unit. The 'family size' that's 30% more expensive but 50% bigger is genuinely a better deal. The 'value pack' that's 20% bigger but 25% more expensive is a worse deal. Most stores don't display this. A quick mental division saves real money over time.
Trust your reaction to the actual price, not the 'savings'
Strip away the discount language and ask yourself: would I pay this much for this thing if there were no sale? If yes, buy it; the discount is a bonus. If you only feel okay about the price because it's framed as 50% off, that's a sign the sale is doing the work, not the value. The cleanest test is whether you'd be happy paying this price tomorrow with no countdown timer.
