I often “save” searches, so that if items are listed that I know are worth a ton, I can snap them up quickly before other people find them! (When you ‘save” a search, eBay sends you an email when new items matching those search terms are listed.)
Recently, eBay introduced a new home page feed. Danni Ackerman of thedanniapp.com created a video that shows you how to set it up. Cool stuff!
