Since you can email the gift certificate to the recipient right when you order it, this is also a boon for those of us who never remember important dates until the last minute. I checked a bunch of different area codes, and there are spas available in tons of places including smaller cities, which is nice if your mom doesn't live in a metropolis but you still want to treat her right.
Want to give your stressed-out best friend in Peoria a massage for her birthday? Or maybe your favorite cousin on the other side of the country's getting married and you want to get her a fancy pre-wedding facial? Instead of having to call around to a million places to see if you can buy one over the phone, or giving away the surprise by asking her, a company called Joy of Spa lets you buy her an "instant gift certificate" that she can use at over 3,000 spas nationwide.
