Giftcards.com is having a massive sale on gift cards, and you don't want to miss it! They're offering discounts of 10-15% on tons of popular brands like Adidas, AMC, American Eagle, Domino's, Hotels.com, and Ulta – basically, something for everyone on your gift list (or, you know, for yourself!). Just use the promo codes EOY10 for 10% off and EOY15 for 15% off on select cards. There are also some various deals with their own codes.

Why should you care? Well, savvy award travelers know that buying gift cards strategically is a great way to maximize your rewards. You can essentially "pre-pay" for expenses you know you'll have anyway (like groceries, gas, or dining) and earn bonus points or cashback in the process.

But wait, there's more! To really maximize your savings, stack these discounts with a shopping portal like Kudos (currently offering 5% cashback at Giftcards.com) or use your Chase Freedom card with Paypal to earn 5x points this quarter. Plus, some cards will also get you 1%/2% back in Giftcards.com Rewards. It's like getting paid to shop!
