Heads up, deal hunters! Amazon is running a targeted promotion where you can score $10 off a $15.01+ purchase just for using your American Express card. The current code to try is AMEXQ4ABC15. The easiest way to check if you're eligible is to click the link provided (affiliate link). If you see the offer, you're golden! If not, it'll error out. The trick? You need to add an Amex card to your Amazon account (or maybe re-add one you removed, as one reader found). This could be especially useful if you don't normally use your Amex on Amazon or if you're looking for a quick win to offset some holiday spending. It's a super simple way to save a few bucks, so it's worth a shot to see if you're targeted! These deals pop up periodically with new codes, so keep an eye out for future offers!
