Free protection for all shopping!

There's a little-known piece of legislation that turns any credit card into a financial self-defence superhero. 'Section 75' of the Consumer Credit Act means your plastic must protect anything you buy for more than £100 for free, so if there's a problem or the company goes bust, you can still get your money back.
And although Section 75 doesn't apply to debit cards, there is something else to fall back on if you've paid using a debit card, or used a credit card for a purchase under £100. Known as Chargeback, this is part of banks' and card companies' internal rules and not a legal requirement. Read full details of Section 75 or Chargeback, plus how to claim, in our guides.

If a link has an * by it, that means it is an affiliated link and therefore it helps MoneySavingExpert stay free to use, as it is tracked to us. If you go through it, it can sometimes result in a payment or benefit to the site. It's worth noting this means the third party used may be named on any credit agreements.
You shouldn’t notice any difference and the link will never negatively impact the product. Plus the editorial line (the things we write) is NEVER impacted by these links. We aim to look at all available products. If it isn't possible to get an affiliate link for the top deal, it is still included in exactly the same way, just with a non-paying link.
