I’m pretty sure I’ve written this one out in some form before, but this is exactly what you need to do to post your FaceBook Fan Page link into your eBay auction/store listing.
1. Start your auctions like you normally would. Get all the way down to description, including filling in your description, before you come back here.
2. Now that you have your product description written you’ll see 2 tabs above marked “Standard” and “HTML”
Click on the tab marked HTML.
