Use it To Pay For the Trip Expenses Planning for a road trip with your friend's then work on how to get the cash back from the journey. When it comes to paying for the hotel stay and the traveling expense, be ready to pay for these expenses. Later ask your friends to reimburse it in cash. There's no added expense for them or you, yet you reap the benefits of the entire group's spending when your next cash back rebate arrives. Even if they want to make some big purchase be ready to pay for it.
