What's happening
ADHD and online shopping can go sideways in the last few minutes. You went on for a phone charger. Then there were "frequently bought together" suggestions, a top-up to reach free delivery and a jumper with 40% off. By checkout, the basket's got six things in it and the total's three times what you planned. Every step is designed to be quick, and the pay-later button makes it feel cheaper today.
How to get moving
Before you press pay, go through the basket line by line and ask one question of each item: did I come here for this? Anything that isn't a clear yes gets moved to Save for later or a wish list rather than deleted, so it doesn't feel like losing it. Take out anything you added only to reach free delivery, too. A few quid for delivery is often less than the extras you'd add to dodge it.
Look closely at the payment options as well. Klarna, Clearpay and PayPal Pay in 3 split the cost, but you still owe the full amount. Since 15 July 2026, interest-free plans like these are regulated by the FCA when the lender isn't the shop itself, so lenders have to check you can afford it and tell you about late fees upfront. It's still borrowing, though.
Important tip
If you do buy something you're unsure about, put the return deadline in your calendar as soon as the order confirmation arrives. For most things bought online from a UK business, you've got 14 days from the day after delivery to tell the seller you're cancelling, then another 14 days to send it back, Citizens Advice explains. Personalised items and food usually aren't covered.
