I have a friend that thought the same thing… That won’t stop people from beating down your doors if they are impatient, and you still have to babysit their can until the approval. It’s even worse if they drag their feet on filing their tax stamp. He’s had a few that have sat for years and the response is always “oh yeah I was about to file my stamp!”. That’s a lot of effort for a few bucks off the top of retail.I would only sell through silencer shop. I would not keep anything in stock. I could also refer people to check with their online account at ss.
