I recently found this website and it might be useful for some members here. It's called Goofbay and it offers various tools like searching eBay seller history and misspelling search. I haven't found any bargains with it but it's fun to play around with. I found there are many ways to misspell Tolkien (just enter Tolkien correctly spelled in the misspelling tool). Examples:

Tolkein (this is the most popular misspelling)
