Can I use AWeber with eBay?
If you want to follow up with people who are purchasing something from you via an eBay auction, make sure that you are getting their permission to do so.
Provided that you have your buyers' permission, you can use the Import feature to add them to your list.
People Viewing "Auctions", "About Me" pages, or "eBay Stores"
By editing the HTML for your auction, About Me page, or eBay Store, you can add an AWeber Sign Up Form.
Note: Prior to putting a form on one of those pages, make sure that you are not violating any of eBay's Terms and Conditions in doing so.
