I literally wait until they tell me my total, type it into the app and spend it right then and there.
In September, in addition to the regular 1-3% they donate they will donate another $50 for every $5000 spent. That is a lot of trips to:
WHOLE FOODS,
MARSHALLS,
HOME DEPOT, ETC
for me, but if we all shop together we can get this done!
If you really get into gaming the system you can shop
for Farm Discovery, then pay with the Benefit app and double down on the money raised. I love that one.
