The Amazon/Chase credit card gets you a 5% Amazon credit for everything you spend at Whole Foods. That pretty much destroys their profit margin on a lot of what they sell. Given that I do all my grocery shopping there (for now), and I spend a lot on food, that's $840/year plus or minus.

My regular Chase card gives me 1.5% of everything I spend back as cash. That's typically about $1k/year.

I pay nothing in (direct) card fees at all.
