How to make eBay RSS Feeds
Do an eBay search as you normally would.
On the results page, set “Sort by:” to “Time: newly listed”. This may not matter, but I think it ensures your RSS feed is updated the instant someone lists what you want on eBay.
Scroll to the bottom of the results page, and look for the orange “RSS” button.
Click the button to add the feed to your reader. Now, whenever what you’re interested in is listed on eBay, you’ll get an RSS update.
That’s it. Hope this helps.
