In order for a product to be sold on Auction Sites (eBay), it must be approved by the original author. We indicate at the bottom of each product page if it has been approved or not.
At the bottom of each product page there is a list of "Distribution Rights", thee is a line item that state "Sell at Auction Sites" [YES] or {NO].
Look for this at the bottom of each product page
Note: Older products may not display the "Distributuion Rights" infomation, as this licensing procedure was not introduced into the resale industry until 1997.
Example:

This is what to look for when determining sellable on eBay or not.
