In the UK, there's all sorts of consumer protection when you use a credit-card - essentially, the credit-card company takes on liability for suppliers' failings. E.g. If you book a holiday on your credit card, and the travel company goes bankrupt, your card provider refunds you. For the most part, those protections simply don't exist if you use a debit-card.
