Was getting ready to make a purchase on OfficeDepot and there is nothing spectacular on any of the points portals (2 or 3x points). I've noticed that TopCashBack usually comes up at the top of the payout percentages for cash-back portals, including 5-6% now for Office Depot. I've used them for a few things recently. Does anybody have any experience with them? I guess what I am asking is, "will I ever actually see my cash from these transactions?"
