Why does it say onthe propel app that you accept credit debit or cash if you dont accept credit?

Use credit at the pump.

I was going in the store she told me that she has to do debit they dont take credit for propel

I've used credit cards to buy propel full at this location MANY times (at the pump). Are you going in the store or paying at the pump?

Because of the system that propel uses it can not be run through the stores main Point of sale System. Hope this helps.

Inside they may not take credit cards.specofocally.for propel or at all opposed to debit just like some ampms JUST started taking credit cards
