This is an interesting idea. This app searches eBay not only the product you
want, but countless misspellings of the product as well. For example, a
PlayStation on eBay will likely be over $150 after bidding has ended.
However, Fat Fingers searches for "PlaStation" and "PlaySation" as well. You
can bid on these misspelled goods that no one else will find, theoretically
saving you heaps. Available for Android, iPhone and iPad.
