I did read the thread.
You don't want to sell on eBay because of the fees.
Local shows don't work because of the costs and no guarantees of sales.
The only reason that people want to sell here is there is no cost. However selling here is not going to happen because of the headaches for the mods even if it is by pm and would be worse if openly allowed.
That leaves two options. Facebook market( no fees), trading for different kits, or doing nothing.
