My Double-Cash card from Citibank used to be my go-to card, but since I do a good deal of my shopping online I got a Paypal card which is managed by Synchrony. It gets me 3% for purchases through Paypal and 2% everywhere else. I got the AmericanExpress Bluecard for groceries but now that they raised the annual fee, I doubt if I will renew. I buy most of my groceries at walmart, Costco or the 99 cent store where I don’t get the 6% back anyhow.
