Meals and gas from Sheetz are often business expenses for me, so I spend a fair amount of time scanning receipts. I've found that a lot of stores wait until a receipt printer is completely dead before fixing/replacing it, giving me receipts that have lines missing and scan/OCR poorly. I'd whine about that, but the fact is that I don't want those paper slips taking up space in my wallet anyway. Why not give the option to skip the paper entirely and email any receipt for a purchase made using my loyalty card to an address I set up on the My Sheetz website?
Include all the transaction details that are on the paper receipt, of course. This would save business folks like myself a lot of time and effort.
