Fitzer is partly right.
If the goods cost £100 and you paid a part of it by credit card, you can claim from the credit card company.
"Here's a quick example of how it works…
Savvy Salma spots the high-tech TV she's been planning to buy at half-price for £500, including delivery, in a high street sale. Yet she's only got £10 left on her card limit (don't worry, it's a cashback card, she's going to pay it off in full).
Salma pays £10 of the cost on her credit card and the rest on her debit card. Sadly the next day the store goes bust, before her telly is delivered. Yet she can claim the WHOLE £500 back from the credit card company, because she paid in part on the card.
Therefore if you want protection…
As long as it costs more than £100, pay for even a fraction on a credit card and you're protected."
