When using the app, we ask that you claim the offer before making your purchase. There are a few reasons why we do this!
Gas stations in GetUpside are changing their offers all the time based on their business needs at the moment you open the app. Gas prices and margins are changing constantly, so the offers in GetUpside change with them. We ask you to claim the offer first so that the offer you're seeing in the app is the exact offer you receive when making your purchase.
Gas stations provide offers to get you to go to their station, and the offer amounts are based on their real-time needs. They want to see that the offer in our app is what drove your business to them. Submitting a receipt for a past receipt doesn't work, because your decision of where to buy gas was already made. Additionally, the gas station's business needs at that past time may have been different, so the offer you claimed now could lose them money.
A similar example would be if you went to a restaurant for dinner after happy hour ended, but asked to pay happy hour prices. The restaurant offers happy hour specials to drive more business during those hours. After the happy hour ends, they don't honor those prices because they're busy at that time and no longer need to use a discount to earn business.
