Can you buy gift cards at grocery store to receive a higher reward rate?
I actually just did that with my Chase Freedom card. They rotate categories every 3 months, and from April-June it was 5% back at grocery stores.  So I bought a ton of gas cards and got my 5% back.  Next I figured out I would be clever and buy a ton of store gift cards (grocery gift cards) right at the end of the quarter, then use those in the future to purchase gas cards.  Well, I just tried that a couple days ago and discovered the store refuses to sell a gift card if you're paying with a gift card!  So now I'm stuck with $1,000 in grocery cards until I use them in actual grocery purchases haha One of the things about this grocery store is they partner with a gas station on their rewards program.  They offer 10 cents off a gallon with every $100 spent in store, and they double it to 20 cents off a gallon if you buy $100 in gift cards.  Then on the back of the receipt is a coupon for 10 cents off per gallon -- which they double on Tuesdays.  Unfortunately I think I'm one of the only people that takes this much advantage of the program  :-/ Side note: I actually just changed the billing cycle of my Chase Freedom card to end on the 24th of the month.  That way I can charge a bunch of rewards in the final 6-7 days of the quarter.  And if I have a $0 balance on the 24th, my bill isn't due for 7 weeks -- interest free!  And Chase Freedom has never cared if you purchase gift cards with their quarterly rewards program.  I also gave them a courtesy email giving the specific store and $$$ amount that was going to be charged, and of course they still called me with a 'fraud alert'...
