I've gotten some pretty good deals off of eBay including: silver charms for a bracelet, a big silver and garnet pendant, a silver and amber ring, a half-price custom made renaissance costume, and a great price on an original (not a CD burn) and unregistered Macintosh OS X Server software set including the manual.
And I must say, the stuff I sell on eBay is usually a pretty good deal too! I just sold a memory chip for an Apple ibook for $24 including the shipping - that same component is currently running about $38 including the shipping via online vendors.
