Updated terms of sale going into each ebay post:
"If you decide to cancel a sale after payment, or elect to return an item, 2.9% of the sale price will be withheld to cover Paypal transaction fees, which are nonrefundable and really, not my *&%%ing problem, but I'm certain you'll see fit to make it my problem, that's why this run-on sentence has been left in 50 pt font, bolded, and colored crimson, so that when you call eBay and complain the underpaid rep from India will be able to easily see that it is indeed unlikely that you were unaware of my policy."
