But credit card fees exist, and will exist regardless of what you choose. Just like filing for your tax return - you can either take the money or let the bank+merchant have it. But maybe you're just too busy to be bothered by reclaiming that money, too?
The amex "I pay $500/y for a 3% card with rotating quarterly 4% and 5% categories" shit though? Yeah, I agree, ain't nobody got time for that.
