LivingSocial Deals is similar to Groupon - they post a local deal every day but since it's the holidays, this one will be up a few more days. The current deal is 81% off a professionally crafted custom teeth whitening kit from the Virginia Center for Cosmetic & General Dentistry in Arlington. They say you save $363 off the regular price of $450 (I figure if it's even $250 regular it's a great deal at just $87). I've been looking to get my teeth whitened and I now is my chance. It says the office is just 2 blocks from Clarendon metro which is also convenient. If you're interested, the link to the deal is below:
