Have always used a Barclaycard with Amazon, and use the points I earn to get vouchers for money off for future purchasers. Was surprised when I saw this.
Not a scam, just one very large company using its power against another very large company. I do not like using a debit card too often, prefer the safety of a credit card. So, have changed this over to one of my other cards which is Mastercard. But no points to be earned. Did get twenty quid off my next purchase with Amazon after making this change.
Do wonder if VISA will crumble before this?
