CVS has been doing email receipts for years, and the only time a receipt prints is if requested. The length of the receipt is due to coupons and extra bucks, so it only prints that long if someone uses their CVS card and chooses to have a receipt printed instead of emailed. They actually have pretty typical receipts for non-card customers.
