One thing to consider.
I find no problem with the Swaps at all. You are not offering anything for sale. It would be best to put up a list stating my Inventory. Then conduct your Swaps via PM.
However anything put up for sale via a post here would be against the rules and would be moved to Classified section if someone complained.
However you boys conduct the For Sale business via PMs same as your Swaps. And all will be well.

So please consider that.
Thanks
