> most people buying stuff on Amazon would be using a debit card, folks only really use credit cards for large purchases Huh? I'm in the UK, have been an Amazon customer for over 20 years and have always used a credit card for everything. I didn't even know you could use a debit card, and can't see any reason you'd want to. Paid off in full every month, better consumer protection, what's not to like?
Here's why: two debit cards, one for receiving money, one for spending money. Automated payment from the 1st one to the 2nd one once a month with a fixed amount you expect to spend in a month. Nothing to pay off, you're spending your own money, can't be overcharged, can't go below zero, if someone leaks your spending card they can't touch the majority of your money, no scummy business practices. Never owned a credit…
You now have perks, points, insurance, consumer protection and still zero worries.
