A couple of years ago, I tried integrating an EBay watch function into this website. Since Ebay lumps all of its golf clubs into one massive category, my idea was to take the Ebay feed and sort it out by manufacturer. It was never very popular, probably because I didn’t have very many categories to choose from. The hand coding was also very difficult, so I never added more.
The idea is done much better at the Steal Golf website. There, the general EBay listings are sorted into more than a hundred (that’s when I gave up counting) categories according to manufacturer. It makes browsing much easier.
