In a popular previous post, I detailed a scam I found where someone was offering a Macbook for only around $5, and were asking for full payment apart from eBay. It was obvious that the deal was too good to be true.
But those 'too good to be true' deals may not be exactly so anymore. If you watch specific item categories, you'll notice that any item with the product misspelled will usually sell for less. This is either because people search with the right spelling and miss it, or they just doubt the credibility of the seller. So these can indeed turn out to be great deals.
Anyhow, it's a pain in the butt to monitor categories, or to guess at misspellings purely in the hopes of stumbling upon a deal. So I thought it was pretty cool that someone came up with the idea of creating an Ebay misspelling search site, where you can search for a specific item, and get all sorts of items with varied alternate spellings.
Try it out, you should be able to find a deal! I know I'll be using the site before I bid on any auctions in the future.
