Turns out you can get $25 back from American Express for spending $100 at Costco. This program is through their Link-Like-Love program, meaning you need to sync an American Express credit card with Facebook or Twitter first and then register for the offer.
But you can really make out big on this offer. You can register multiple American Express cards, and you can get your $25 statement credit by buying a $100 Costco gift card online. So it’s like a $100 card for only $75, multiplied across as many American Express cards as you have. UPDATE: As someone noted in the comments, you’ll need multiple social media accounts since you can only sync one card per account. However, it’s fairly easy to set up multiple accounts. Facebook supposedly wants each person to only have one account; I signed up back when it was college students only, so I have no idea how hard it is to do this anymore. But I do know it’s easy to set up multiple Twitter accounts. Deals We Like has a good introduction to getting started with Link, Like, Love.
Use this trick to save a bunch as you stock up on Christmas gifts, wrapping paper, gas, or even just buying already discounted travel and restaurant gift cards. I actually need to go back and buy some more WallyPark gift cards sometime in the near future.
Sadly you cannot use a Costco gift card to buy a $1.50 hot dog and soda… I guess you just pay in advance at the register.
