The receipts also help to establish a rough timeline for 3DO releases, which is something that is not well documented. Obviously, they don't dictate absolute release dates, but they do create a sort of upper limit to when the title was released since the game had to be available when the receipt was printed (excluding predorders).
If anyone else has receipts for 3DO hardware/software I encourage you to scan them and include them in this thread.
