Look Up "Alternate" Spellings
eBay offers a lot of services—a comprehensive spell check is not one of them. So if a seller wants to list his priceless OG Air Jordan 1 samples under "size 9 air jordon sneakers," no one's going to tell him otherwise. Put those typos into the search bar and see what comes up. Likewise, it's amazing what can be found sometimes by searching things like "vintage basketball sneakers" and "old tennis shoes." Go deeper.
