Although Groupon and other discount sites sometimes get a bad rap among spa owners, others swear by them. As a consumer, I must admit I'm a fan, having benefited from numerous online deals over the years. In fact, just today I came across one from TravelZoo offering a regularly priced $70 Hot Stone Mani and Pedi with wine for just $25 at Village Nails & Spa (New York City). Needless to say, it caught my eye, as I'm sure it did many others, as well. That isn't to say I haven't had my share of regrettable experiences with various deals. However, it's those businesses that embrace my patronage, regardless of how they came by it, that are the same ones I choose to frequent, whether I've received a discount or not. What positive or negative experiences has your spa had with online group discounting deals?
