I'm a disabled vet that can not make ANY money, without it causing problems for me.
Then there is absolutely no way I would use my account to sell items on their behalf.
They are telling me that I have to take commission to help them, because of Ebay rules?!?
What eBay rule is that?
how can I donate the commission back to the NFP without it showing up on any records?
I would tell the NFP they need to create their own account attached their own bank account, and give you access to it.
