It may be theoretically possible, but it's probably more hassle than it's worth. It's easier for inventory tracking if you have a paper trail (or equivalent on disk). It's also good to have the receipts if you're ever audited. It's also inconvenient for the 99.999% of customers who aren't trying to cover their tracks, because without the info they wouldn't be able to check their order history. And it's not simply a matter of telling the law enforcement agency "We don't store that information." You most likely have to jump through the hoops to prove that you don't store the information.
