You can get another 5% back with the Ibotta App.
Also, I use giftcardgranny.com I to find deals on discounted gift cards which I buy in advance for stores where I know I will shop. I've gotten Joann's gift cards for as much as 28% off, although today the best deal seems to be 5%). I also order up cards for gas, department stores, and discount stores in advance.The savings add up pretty quick.
