I have dealt with TMR twice recently. Both times were great. I was selling a turntable that when they received, there was an issue with the motor not keeping a constant speed. They said it was taken care of by their tech and no charge.
As far as the issue with 1099’s I was advised that the threshold had been changed back to the $20,000 and 200 items sold before one would be issued at least by eBay. Not sure how other establishments would report unless it is up to you to self report!!!!
