I thought Groupon was supposed to be a discount deal... Found a Groupon for full leg wax (both legs) at a local salon for "50% off" - $35 (originally $70). I called the salon, did *not* mention Groupon, just asked how much leg waxing was. Both legs, full leg wax is $25. Looks like a Groupon scam to me...
Had another experience about a year ago for a body massage. 5 out of the 5 locations listed for my area no longer accepted Groupon. Groupon did refund my money, reluctantly.
I think I'm done with Groupon. Too much work to make sure you're getting a deal, and checking to make sure the business accepts the Groupon.
