Really disappointed with this Groupon. Purchased 6 sessions but was told by the merchant that it is actually only 3 sessions if used on legs. Apparently 1 session per leg is required, 2 total with each visit. I've purchased other Groupons in the past for similar services and 1 session always included both legs. If I had only purchased one session, would the merchant have only worked on one leg? This Groupon is completely misleading.
