The savings that we show are the estimated amount aggregated from the data we receive. We strive to be as accurate as possible and to this end, we also allow you to indicate some options like quantities and types of services you are redeeming so that we can more accurately identify your savings. Having said that, we will not be able to know precisely the actual spending done at the store. In most cases, we get the feedback that the members' actual savings are higher than what we estimated.
