Advertise this program with only ebay tools?

:?: Using only ebay tools, best way to advertise this program :?:

What ebay tools were you wanting to use?

Hi, I have a ebay store(basic) and I sell coins & antique glass. I dont have a web site yet, but Im really impressed with the Slaehoo. I wondered if there was a better way to advertise the program using the basic listing form for items. I had thought of a prety good ad for it but wondered if it was ok to paste a free link to Salehoo.
