I got one vendor like that. They have left a bad taste in my mouth per say about their after market belts where every one is shorter than spec'd.. At they still got blades that are right plus the Briggs parts are still reasonable. Anyway the sales to me has dropped from 3500 usd per year to right at 2000 usd this year and they will be dropping further next year; unless, things change for the better. I know that don't sounds like a lot but my actual parts purchase is at least 50% this year as I have rerouted purchases to other vendors.
If you pay enough attention to your purchases you will find other tricky vendors too.
