Hotels.com 20% Off AMEX Offer
New AMEX offers are out. Many of the offers are niche-based, but almost everyone (reading this) will be interested in the Hotels.com gift card deal. Spending at least $50 will net you a $10 statement credit or 20% back. Hotels.com allows you to combine gift cards as well, so if you have multiple AMEX cards, you can stack this offer.
+ Keep in mind that Hotels.com bookings generally don't get you any hotel loyalty points, but if you can get a great deal, or if you're going to place that doesn't have the chains you use (for me I'll use this for my summer Cuba trip!), this can be an excellent deal.
+ You should also check your email for targeted offers. I received one for $50 off $250 of spend on a hotel booking, which also amounts to 20% off. Cuba is getting cheaper and cheaper for me by the day!
