When you're on the hunt on eBay and Craigslist for a specific item, but you're either waiting for that great deal or the perfect match, you've got to use TypoBuddy. Enter your search into TypoBuddy's page, and the site comes up with the ads on eBay and Craigslist that have been misspelled in some way, and voila! There's a whole host of items you never would have seen due to your (ahem) perfect spelling. I've heard the advice before to try typos in an item search, but TypoBuddy utilizes so many more possible combos, like twice-typed, transposed, and missing letters.
The great thing is, other people are unlikely to see these items, bumping up your odds of finding and owning the perfect "Daneish Credenxa."
