Please be careful using this app, at first it was doing well but after a few uses later the amount starts to change, it over charges the amount you enter then you have to wait 13 for a refund
And the worst part, when the merchant doesn’t charge you zip still does, I got a partial credit and they said I would only receive the rest of the credit if they receive an email from that company that it wasn’t charge, so currently my bank is disputing this with them and zip had closed my account..
