Do you think retail stores intentionally use disappearing ink on receipts so that when customers take them up on merchandise warranty, the store can easily deny them because they have no receipt or at least it's not visible? I've noticed several of my receipts the print is barely visible and these receipts are only a year old. I've decided that I should at least scan them for archive so I have some sort of proof. I can at least use copies for manufacturer warranty. My problem is I bought extended store warranty. So I do need the original receipt to bring to the store.
