We use out Paypal Debit cards for a lot of our purchases. PP is great. Flat 1% cash back on anything ran as credit, but more importantly, you get an email receipt IMMEDIATELY after every purchase. Like, you can go through the McDonalds drive thru, pay with PP card at 1st window, and by the time you have your food in your hand, your phone is going off with an email alert telling you where, when, and how much was spent. We have had 1 single issue with a fraudulent charge with the card, and PP reversed it almost immediately with out much hassle.
It works for us because most of my GF's income comes through PP, as well as the income from my side gig.
