Discover - Credit Card Review

Okay, Discover isn't accepted every where, but it is accepted in enough places for me. I try to use it for larger expenses so I get more cash back. I have only used cash back to pay off my bill because it's most convenient.  I don't want to deal with small checks arriving by mail.  The little folding card was a nuisance and i don't ever use it, but carry the standard-size card.
