When you've been on eBay for awhile, you will find that certain sellers carry a type of merchandise that interests you. By saving their user IDs in the My Favorite Sellers area, you'll be able to revisit their current auctions without having to run a seller search from the search area. Remember that the purpose of the My eBay page is to have all your controls in one area.

From a seller's point of view, My Favorite Sellers is where you can keep a list of people who sell items similar to what you sell. You can check up on them and see what they're selling, when they're selling it, and for how much. It's a helpful tool that can prevent you from listing an item right next to one of their auctions.

My Favorite Sellers is handy also when your competition is selling an item that you plan to sell, but at a deeply discounted price. When that happens, don't offer yours until they sell out of the item, at which time the price will most likely go back up -- supply and demand, remember?

To add a seller to your My Favorite Sellers list, click the Add new Seller or Store link in the upper-right corner of the page. On the page that appears, type the seller's user ID or store name. You may add a maximum of 30 sellers to your list.
