GarageSale will help from the very beginning because it offers even a template creator to create your e-shop in eBay.
It offers a WYSIWYG editor that grants you total control during the editinon of the page, so you can create a very attractive one.
Of course, you'll be able to control those products on sale, view bids and know everything about them within one click.
GarageSale is a good companion when selling on eBay.
For Mac OS X 10.4 or higher.
