I bought groupon package for laser hair removal. It is good for that first few treatments but then there is this rule like , if you buy groupon once , you cannot buy it for second time and you have to take membership or pay in installments which costs you more for the same treatment. I never went again to simplicity. Timings are also not flexible. It is always booked fully in advance. It would be good if there are monthly rates instead of packages. We never know for how many months we can continue at same place.
