They are few and far between, and only account for about 0.01% of the eBay user population among sellers, however I feel it is my duty to share my findings with other ebay users.
For those who don’t know a “Santa Claus User” on eBay is a user who sells stuff for way cheaper than he/she could sell them for, and does it just because they do not need the money or because they feel it is a good gesture on their part. For example, check out the screen-shot below…

Notice, this seller is selling a $1,200 processor, the Intel Core2Duo Quad QX9775 for only $500. If you do an eBay search for “QX9775″, and filter to show only the “Completed Listings”, you will notice that the cheapest used processor of this model sells for around $900 or $800 at its lowest. Well, I also had the fortunate chance to purchase an item from this user as well. He was selling an Intel D5400XS motherboard, brand new, for $350. The same motherboard, sells from TigerDirect.com for $609 and from NewEgg.com for $600. His eBay userid is “songmin” and he only sells a couple items at a time usually, always electronics or computer parts, but his prices are lower than low. Who knows, he might be stealing them, but he is a power seller, and I don’t care where the items come from as long as I am getting a good deal. So, if you are looking for parts, or building a new computer perhaps, keep this guy in your watch list, and check him periodically.
The explanation I got from him was that he is a medical/ER doctor and just does this on the side, as a hobby, but not as his chief money maker. I had to share this with other ebay users, as he is my go-to goldmine for good deals on brand new and lightly-used equipment.
