A big red "70% off" label is designed to make you buy now. Sometimes it is a genuine bargain. Often it is a normal price dressed up as a discount, or a cheap price on a product that is not quite what it seems. Smart shoppers judge a deal by facts: what the item has actually sold for, what it costs in total, and whether it is the product they want.
Start with price history
The single most useful question is: what has this item sold for over the past few months? Price history turns a vague feeling ("that seems cheap") into evidence.
- Price tracking websites and browser extensions record prices on popular retailers over time and show a chart. Many also let you set an alert for a target price.
- Retailer wish lists often notify you when an item drops in price.
- Your own notes. For a planned purchase, jot down the price you see each week. It is low-tech but works on any site.
When you look at a price chart, ask whether the current price is near the lowest point, whether the "original" price was ever actually charged for long, and whether prices tend to dip at certain times of year.
Price trackers and extensions can be very useful, but check what data a browser extension can access before installing it. Choose well-established tools and remove ones you no longer use.
Beware of fake "was" prices
A reference price, the crossed-out "was" or "list" price next to the sale price, is only meaningful if the item was genuinely sold at that price. Common tricks include:
- Raising the price shortly before a sale so the discount looks bigger.
- Comparing with a "list price" that almost nobody ever charges.
- Permanent "sales" where the item is always discounted from a price it never sells for.
- Countdown timers that reset every time you reload the page.
In the US, the FTC has long-standing guides against deceptive pricing, and some states have their own rules on reference prices. Other countries regulate this too. Enforcement is patchy, though, so price history is your best defense.
Compare the total cost, not the sticker price
The cheapest item is not always the cheapest purchase. Before you compare offers, add up:
| Cost | What to check |
|---|---|
| Item price | For the exact variant, size and quantity you want |
| Shipping | Including any minimum order for free shipping |
| Taxes and duties | Especially on international orders |
| Accessories | Batteries, cables, chargers or parts that are "sold separately" |
| Return costs | What it would cost to send it back if it is wrong |
For orders from abroad, our guide to shipping, customs and import fees explains what extra charges can appear.
Make sure it is the same product
A cheaper listing is only a better deal if it is the same item. Price differences often come from a different model, a lower-spec variant, an older version, a refurbished unit or simply a part rather than the whole product. Compare model numbers, specifications and what is in the box.
Be skeptical of very large numbers in product titles, too. Marketplace titles sometimes advertise headline figures, such as magnification, capacity or power, that are hard to believe at the price. In the example below, one monocular lists a modest specification and another lists a far bigger one. Do not assume the bigger number is the better deal. Read the specification table, look at buyer photos and reviews, and judge what the product actually delivers. Our guide on how to spot counterfeit products has more on comparing listings.
Coupons and promo codes
- Check the store's own offers first: newsletter sign-up discounts, store coupons on marketplace listings and loyalty programs.
- Use coupon sites carefully. Many listed codes are expired or never worked. Do not let the hunt for a code tempt you onto unfamiliar sites.
- Read the conditions: minimum spends, excluded brands and expiry dates.
- Do the math. A coupon that pushes you to spend more to reach a threshold is only worth it if you wanted the extra item anyway.
Sales events: plan, do not panic
Big sales events can bring genuine discounts, but they also bring the most aggressive marketing. To get the real benefit:
- Make a list of things you actually need before the sale starts.
- Track their prices for a few weeks beforehand.
- When the sale arrives, check the price history again. A real deal is clearly below the normal price, not just below an inflated "was" price.
- Ignore countdown timers and "only 2 left" messages unless you were already planning to buy.
Remember that many items go on sale several times a year. Missing one event usually just means waiting for the next.
Cashback, price matching and price adjustments
Some credit cards and cashback programs return a percentage of what you spend at participating stores. Some retailers will match a competitor's lower price, and some will refund the difference if the price drops shortly after you buy. Policies vary and change, so check the details before relying on them.
When a deal is too good to be true
An extraordinary discount on a popular item from a shop you have never heard of is a classic scam pattern. Before buying, search for the shop independently and pay with a protected method. Our guide on online shopping scams to avoid lists the warning signs. The FTC also has practical advice on shopping online.
Summary
- Check price history before trusting any discount.
- Treat crossed-out "was" prices with skepticism.
- Compare the total cost, including shipping, taxes and accessories.
- Make sure you are comparing the same product and variant.
- Plan for sales events instead of reacting to them.
