There are even websites dedicated to the typo search phenomenon. Plug your search term (for instance, "Eames") into one of these sites, and it will search eBay or Craigslist for all of that keyword's most popular misspellings (like "Ames or Emes"). Each of these sites supports multiple countries (and cities, in the case of TypoBuddy and Craigslist):
Of course, if you'd rather work manually to find a real diamond in the rough, here are a few of our favorite misspellings for popular homewares and furnishings.
• armoir, armwore, armiore (armoire)
• coach (couch)
• shays lounge (chaise)
• dinning room table
• i pod (instead of one-word iPod, you might also try "i pad" and "i phone.")
• Xbox Connect (Kinect)
• automan, ottomen (ottoman)
• shelfs, shelve
• suade, swade (suede)
• rot iron, rod iron (wrought iron)
