Had some fun last night and typed in the word "gadget" on eBay. Didn't think that much would come up, but I was shocked to see 3,468 items listed! That's right -- more than 3,000 items had the word "gadget" in the listing title. (Obviously there are many thousands more gadgets for sale, but not with the word "gadget" in the title.)
The most expensive: 3D glasses for $1,024.34 -- they must really work!
The least expensive: A pen lighter for a penny.
