I've mentioned Giftybox before, but if you're new to the concept, here's the scoop: you buy a Giftybox, which lets you choose from more than 200 spa and wellness treatments (facials, massages, life coaching, and so on) at the venue of your choice. Participating locations are in Atlanta, Boston, Chicago, Dallas, Denver, Houston, Los Angeles, Miami, New York City, Philadelphia, San Diego, San Francisco, Seattle, and Washington DC — so if you're near a major metropolitan area, you're set.
It's already a fun idea, but until May 10, when you buy one spa Giftybox, you'll get a second one for free. Do the math — that's two spa visits for $89, which means that you and your mom can each have a girly adventure for the price of one. Buy online and use the code MOMSDAY2009 to get the freebie. Good times.
