I bought a computer with a certified check that was too large once, and eventually I did get the store to take it, and promise a refund from their central office. I think it was months later and I had to call them up to get my refund, but it did actually work out. That was in the 90s and of course I would never do it again. It clearly was a well known red flag even back then.
