Gotta give a thumbs up to to Citi Double Cash card, nice to be able to redeem for statement credit monthly versus waiting for the Costco AMEX once a year cash out. The Citi MasterCard is now our go to card for pretty much everything, dining, shopping, online. Use to think its gimmicky with the 1% up front and then another 1% after you pay off. But just noticed when you get the 1% from paying off, you also get the 1% from the new statement close. So basically except for the first month, you are getting 2% every time.
Benefits seem similar to AMEX as well with the 1yr (iPhone) extended warranty, travel, and something I haven't seen before:
60 day return guarantee (have to manually enroll). Need to look into it more, but basically you can get your money back by returning any unsatisfied item to them. Interesting.
They also have a online receipt upload database for your 1 yr extended warranty products.
