Like everyone else, I am trying to maximize my points from category spending with specific cards. Is there a list of what cards are good for what categories? I am pretty new to this, so let me know if this info already has been compiled. I tried searching, but couldn't find anything. Here are ones I know of, but I would appreciate insight into others.
