interior upholstery

Yes it makes sense. Tooling cost plenty of fronts get damaged so more sold
You have to sell quite a few to even recoup the cost and be even. Plus warehouse them forever till they sell thst a major expense as well as taking space that can be used for fast moving stock.
I can't see why you couldn't send in your old panels to get recovered. They already have the material available. I don't mean to sound ignorant, but they offer the door panels for darts, duster's and a couple of others, so I think that's a poor excuse.
