With this kind of thing, here's what I worry about: what if the store decides to charge you $X+5, where the real price is only $5? When a receipt is handed to me at point of sale, I can catch anything different there and bring it up then. After that, I know the receipt is good. Who would pull out their phone to check their email and make sure the receipt is valid?

Good point. For everyone who actually wants to check the receipt at the POS there is an option to also receive a paper receipt (i.e. email and paper). If the receipt is ok, you can throw away the paper receipt and keep the email receipt for potential future changes/returns/expense claims etc. Now this defeats the environmentally benefit of email receipts but is a way around it. Some retailers let their customers look at customer-facing till screens while scanning the purchase items.
