So the cardpointers I used mainly to ADD the special offers to my cards. I have 5 Amex cards, and between my Chase personal/business, I have I think 10?

So rather than logging in 3 times and manually adding offers to each card individually, I bought the Cardpointers+ (BTW, only works with Chrome) extension so that I only have to login 3 times (once for Amex, once for Chase Personal, once for Chase Business) and it has an option to add all offers to all cards.

Then, of course, there's the trying to remember/know what's on what card. If you continue to use Chrome to buy things online, it'll pop up and tell you which card (Amex/Chase, and now Citi) to get the "best" deal.

I've NOT used their app that heavily to be honest, but it seems to be fairly similar if you can remember to check it when you're buying stuff at stores.
