How to target ads to Ebay and Amazon sellers? How to get email addresses or how to target ads to them with Facebook or ....
Ebay and Amazon sellers are probably hanging out on social media sites. Try twitter. The right ads with the right hashtags may reach some of them. (Use hashtags like: #PowerSeller #EbaySeller #AmazonSeller #HowToSellOnline #EbaySuccess #AmazonSuccess).
I would try web forums for ebay and amazon sellers. http://www.aspkin.com/forums/ http://www.webretailer.com/ Some probably sell ad space contact them and ask them to place an ad.
