Heads up, deal hunters! Amazon's running another targeted promotion where you can snag $10 off a $15.01+ purchase when you use an American Express card. The current code to try is AMEXQ4ABC15. Just add an Amex to your Amazon wallet (or re-add it if you've removed it!), load up your cart, and apply the code at checkout. Now, here's the catch: this isn't for everyone. Amazon seems to be targeting specific customers, possibly those who don't have an Amex linked to their account or those who recently added one. The best way to see if you're eligible is to click the link and see if the offer pops up. If it errors out, you're probably out of luck this time. This offer is a pretty sweet and easy way to save some cash on Amazon, especially with the holidays coming up. So it's definitely worth checking if you're targeted. And if not, keep an eye out for future similar promotions – they seem to pop up every few months with new codes!
