Discount codes are one of the easiest ways to save money online, but using one without checking a few basic details first can lead to a wasted trip to checkout, or worse, an unsafe website. Here’s a short checklist worth running through before you enter a code.

1. Is the code for the right retailer and region?

Codes shared online are sometimes for a different country’s version of a retailer’s site, or for a related but separate brand. Check that the code is intended for the UK site you are shopping on before assuming it will work.

2. Does the source look trustworthy?

A code posted on the retailer’s own site or a well-established deals site is generally more reliable than one from an unfamiliar page, particularly if that page asks you to complete extra steps before revealing the code. If something about a site feels off, it is safer to search for the offer elsewhere.

3. What does the code actually apply to?

Check whether the code applies to your specific items, or whether it excludes sale stock, certain brands, or has a minimum spend. This is usually shown in the terms next to the code, and it is worth reading before you get to checkout rather than after.

4. Can it be combined with other offers in your basket?

If you already have a sale item or another promotion applied, check whether the code can be stacked on top of it. Many retailers only allow one discount per order, so it is worth knowing this in advance rather than being surprised at checkout.

5. Are you being asked for anything you shouldn’t be?

A legitimate discount code should never require payment details or extensive personal information simply to reveal it. If a site asks for more than an email address, treat it with caution.

CheckoutDeals lists current codes with their terms shown upfront, so you can check most of this before you even click through to a retailer.
