> You absolutely can, that's the entire point of receipts. If the seller refuses, that's where trade law comes into play and you can sue. 'Sales are final' is a trade statement; in most U.S. states under most conditions you cannot return an item when this is stated (even if you have a receipt). > This of course, isn't a great comparison because in the modern day cash is almost never used for anything other than small transactions (or by the uber paranoid). To even be close to the same you'd have to compare it to putting cash into an envelope and mailing it. Not exactly a common practice. Many people around the world still use cash for most of their transactions. And, as couched, the economy still functioned perfectly fine 30+ years ago where most people in the developed world used cash for most of their transactions as well.
