10 online shopping tricks stores use—and how to beat them

Online shopping is supposed to make life easier, but a lot of the design is built around getting you to spend just a little more than you planned. It's not your imagination-there's a whole field of "dark patterns" that nudge you toward choices that benefit the store more than they benefit you.

You don't have to turn into a conspiracy theorist about it, but it does help to know what you're looking at. Once you see these tricks, it's hard to unsee them-and easier to keep your money.

1. Free shipping thresholds that push you to add "just one more thing"

Free shipping is the number-one perk people care about when shopping online, and retailers know it. A lot of them set a minimum-$35, $50, $75-and quietly count on you adding extra stuff just to hit it. One study found shoppers spent about 9-10% more trying to reach a free-shipping minimum.

Beat it: Put what you actually need in the cart, then compare the shipping cost to the price of extra items. If shipping is cheaper than padding the order, pay the shipping and move on. Or keep a running list of true staples (toilet paper, detergent, diapers) so you're adding things you'll use, not random fillers.

2. "Only 3 left!" fake urgency

That little "only 2 left in stock" or ticking countdown timer might be real, but it might also be there to make you panic. Research on dark patterns shows scarcity messages are one of the most common tricks used to hurry people into checking out.

Beat it: Ask yourself, "If this was still here next week, would I actually care?" If the answer is no, close the tab. If it's something you truly need and have been planning to buy, go ahead-but don't let a timer make the decision for you.

3. Drip pricing and hidden fees

Drip pricing is when you see one price at the start and more fees show up later-service fees, resort fees, "convenience" charges. It's common in travel, tickets, and some marketplaces, and regulators have started cracking down on it because it misleads people about the real total.

Beat it: Don't compare options by the first price you see. Click all the way to the final checkout page and look at the full total, including fees. Only compare final numbers across sites.

4. "Buy now, pay later" that doesn't feel like real money

BNPL (Buy Now, Pay Later) makes it feel like you're spreading out the cost harmlessly, but the debt adds up fast. Americans spent tens of billions through BNPL in 2024, and a big chunk of users reported missing payments or getting hit with fees.

Beat it: Treat BNPL like a credit card: if you wouldn't put it on a card and pay it off quickly, don't break it into installments either. If money's tight, put the item on a 48-72 hour list and revisit it when the "I want it" feeling isn't so loud.

5. Pre-checked boxes for add-ons

Some sites automatically check boxes for things like insurance, donations, extra services, or newsletters. If you're rushing, you pay for or agree to things you never actually wanted.

Beat it: Before you hit "Place order," scroll back through and read each line item. Uncheck anything that you didn't deliberately choose. It takes 20 seconds and can save you a surprising amount over a year.

6. "Recommended for you" bundles that double your cart

Those little "Customers also bought" or "Frequently bought together" boxes are there to raise your total. Sometimes they're helpful. Sometimes they push you toward higher-priced versions or add-ons you won't use.

Beat it: Decide what you need before you start scrolling. If a recommendation lines up with something you were already planning on (like batteries with a toy), fine. If not, leave it.

7. Fake compare-at prices and "limited-time" sales

You'll see an item "marked down" from a high price it almost never sells at. Investigations have found plenty of examples where the "original" price was inflated just so the sale looks better.

Beat it: Use price-tracking tools or a quick search to see what the item usually sells for at other stores. If everyone else is selling it around the "sale" price, you're probably not getting the deal you think you are.

8. Tricky subscription checkouts

Some sites nudge you into a subscription instead of a one-time purchase: the subscription option is highlighted, the one-time button is tiny, or you get a "best value" badge only on the recurring option.

Beat it: Slow down and look carefully at how often you're agreeing to be charged. If you only need it once, make sure you've actually chosen "one-time purchase." Immediately set a reminder in your phone if you do sign up for any subscription intro deal.

9. "Only X more dollars to unlock…" extras

You'll see banners saying you're just a few dollars away from free samples, bonus points, or a small discount on your next order. It's the same psychology as free-shipping thresholds-get you to add more than you planned.

Beat it: Ask, "Would I buy this extra item right now if there were no reward attached to it?" If not, skip it. Bonus points and samples aren't free if they require you to overspend first.

10. Endless emails and push notifications calling you back

Abandoned-cart emails, app notifications, "price drop" alerts-once you've looked at an item, the site will chase you. These aren't always bad, but they can pull you back into shopping you were done with.

Beat it: Unsubscribe from stores you overspend at, turn off app notifications, and set a rule for yourself: if you didn't already plan to buy it this month before the reminder showed up, treat it as a "maybe later," not a to-do.
