or I could just use a couple coupons at the grocery store and get a couple bucks in savings
it's an interesting idea but one where your time is worth more than a couple bucks. lol
or I could charge more of my other itmes instead of cash. My rewards aren't as good as they used to be. I had a card a few yrs ago that literally was paying me 5% back at grocery stores. IT totally rocked, but now it's like 2% or less.
