Hey awardtrail readers, listen up! Amazon's running a promo where you can snag a $20 credit if you spend $100 or more on select items. Sounds great, right? Well, before you go on a spending spree, there's a little asterisk. The selection of eligible items is… well, a bit random, according to Doctor of Credit. So, this is where your savvy traveler skills come in. Don't just assume you're getting a deal because of the $20 credit. Price compare those items with other retailers to make absolutely sure you're not overpaying in the first place. Think of the $20 as a potential bonus, but do your homework first. A deal isn't a deal if it's still more expensive than what you could find elsewhere. Happy shopping (responsibly)!
