Discover - Discover Card Cashback Bonus Review

I have been a member with Discover Cashback Bonus Card for more than seventeen years and must say they always treated me with respect. I once had a problem with redeeming my cashback thru their internet connection with AMC Theatre Tickets, for some reason or another I did not receive the tickets and after six weeks I called discover card and explained my problem.  They resolved my problem without further ado and I received my new tickets within one week.  So far this was only one problem I had in seventeen years.  I always sign up for their special promotions, such as getting double bonus cashback for shopping at my favorite grocer or hardware store and so many more, also getting five dollars back in addition to regular cash back, for shopping at a new store that started excepting discover card.  Signing up is so easy, one can do it by simply paying a bill over the phone, free of charge by the way, which I find very convenient and fast.  One can pay via phone the same day the bill is due, is this great or what?  Also cashback bonus adds up fast when you pay recurring bills with discover card, such as phone, utilities, grocery, cable tv, car insurance, just to name a few. I am very happy with discover card.
