They try their best to not give $ back constantly finding issues with the rewards even when use a linked card.VERY MISLEADING APP. DO NOT WASTE TIME AND EFFORT DOWNLOADING. You only have 1 place to chose from shell stores only. Plus you get screwed on $ if you use card like discover or even the shell rewards card because upside either cuts your actual $ does not pay out at all because of the so called rewards you earned with other promotions. Once i earn enough to get paid out i am deleting app.
