The OP does not need to buy a new belt. The solution is simply to wash it in warm soapy water then rinse & dry and it will be good as new
You may be correct, moonglum, but you can't know that for sure unless you've actually examined the belt. Even the best belts do stretch over time and require replacement. That's part of why they sell replacement belts. I usually get more than a decade out of mine and you're correct, the soapy water wash often restores it satisfactorily. But all things wear out over time.
