I love Groupon. I have done so well with getaways, dinners, family outings, salon treatments. I have had nothing but excellent experiences with my Groupons. My one gripe is when receiving med spa services, some places stipulate tipping on the full amount of service (not the Groupon price). I'm sorry, I just don't agree. Some of these Medical spa treatments like I-Lipo or Lipo-Ex are way over priced and extremely brief services with little to almost no work for the technician administering these services. Many require getting laser paddles strapped on to the body and the timer set on the machine and the technician leaves the room. I was a bit resentful of the somewhat demanding note posted on the wall of one med spa office. I use Groupon because I would not otherwise be able to afford these over priced med spa services and to have to add a $75 tip for a 20 minute treatment is just ridiculous and defeats the purpose. It also makes me wonder what sort of service I will get on my second treatment because I gave a tip based on what I paid for the Groupon.
