The internet is packed with "deals" that aren't. Fake countdown timers. "Was $199, now $49!" on something that was never $199. Coupon sites listing 40 codes for a store, 39 of which expired during the previous administration. Here's how to save real money instead, using the rules retailers and regulators have actually published.
1. Know the real price before you get excited
A discount is only a discount compared with what the item usually costs. Before you buy anything pricey:
- Check a price history tool. Price trackers (CamelCamelCamel and Keepa are well-known ones for Amazon) chart an item's price over time, so you can see whether today's "sale" is a real low or a Tuesday.
- Check the brand's own store. Brands run their own promotions. When we checked in October 2026, for example, Logitech's store showed its G502 HERO mouse on sale for well below its $69.99 list price.
- Be suspicious of round, giant "was" prices. If the "original" price seems made up, it might be.
2. Use price adjustment policies (the most underrated trick)
Some big retailers will refund the difference if their own price drops soon after you buy. Policies change, so always read the current version, but as of October 2026:
- Best Buy's Price Match Guarantee covers drops in Best Buy's own price during your return-and-exchange period. For most products that's 15 days, longer for paid My Best Buy members, with exclusions like Marketplace, open-box and clearance items.
- Target will adjust to a lower Target price (in store, on Target.com or through Target Circle deals) within 14 days of purchase. Target stopped matching competitors like Amazon and Walmart in 2025, so the old "show them the Amazon price" move doesn't work anymore.
The move: after a big purchase, set a phone reminder for day 10. Check the price. If it dropped, ask. It takes five minutes and can pay better than any coupon.
3. Treat coupon extensions with healthy suspicion
Browser extensions that "automatically find coupons" sound like free money. Sometimes they are. But in December 2024, a widely watched investigation by YouTuber MegaLag alleged that PayPal's Honey extension replaced creators' affiliate tracking cookies with its own at checkout, and that partner stores could control which coupon codes Honey showed shoppers. Reporting from The Verge and Snopes followed, and class-action lawsuits were filed. PayPal has said Honey follows industry rules and practices. Those disputes are about how the extension works, not proof that every coupon is fake.
The takeaway isn't "never use an extension." It's this:
- An extension that says it found "the best price" may only be showing codes a store approved.
- Extensions can see a lot of your browsing. Install only ones you trust, and remove the ones you don't use.
- The store's own email list or app often has the real first-order code.
4. Dodge coupon-site and fake-store scams
- "Too good" social media ads. A brand-name item at 80% off from a site you've never heard of is a classic fake-store setup. Search the store name plus "scam" or "reviews" before you pay.
- Look-alike web addresses. Check the address bar. "stanIey" is not "stanley."
- Pay with a credit card rather than a debit card, wire transfer, gift card or payment app. Credit cards generally give you stronger options to dispute a charge if something goes wrong.
- Coupon sites that want you to download something or "verify" with your personal info. Close the tab.
5. Don't trust stars blindly
Fake reviews are such a problem that the FTC finalized a rule banning them, which took effect in October 2024. It prohibits things like fake or AI-generated reviews from people who don't exist, and buying positive reviews. Rules help, but you still need a sharp eye:
- Read the 3-star reviews. They tend to be the most specific.
- Watch for lots of five-star reviews posted in a short burst with similar wording.
- Prefer reviews that mention how long the reviewer has used the product.
(For the record: Prudent Deals doesn't publish customer reviews or testimonials. Our guides compare official specs and prices, and we say so.)
6. Watch for drip pricing and sneaky fees
The FTC's rule on unfair or deceptive fees took effect in May 2025. It requires the total price, including mandatory fees, up front for live-event tickets and short-term lodging like hotels and vacation rentals. Elsewhere, you still need to click all the way to the final checkout screen before you compare prices. A $5 cheaper item with $12 shipping isn't cheaper.
7. Subscriptions: the quiet budget leak
- Set a reminder the day you start a free trial. Trials are designed to roll into paid plans.
- Know the refund window. For example, Coursera's annual Coursera Plus plan has a 14-day refund window, and MasterClass offers a 30-day satisfaction guarantee on its annual plans.
- Prefer monthly if you're unsure. Annual plans are cheaper per month, but only if you actually use them all year.
8. Ask yourself the Prudent question
"Would I buy this at full price?" If the answer is no, the discount isn't saving you money. It's just making spending feel like winning. Our slogan is Shop Prudent. Play Hard. Save Big. The first part does most of the work.
