The offer that you have on groupon should be wholely utilised on its on without the need to purchase additional services or goods. I found that the offer was not a true discount offer as the initial consultation found that a series of appointments are needed which the voucher didnt cover. The voucher was only for 3 appointment. So I feel that the offer was misleading to begin with because min no of appointment required are at least 6 in most cases, so this should have been disclosed from the beginning. The offer should be such that a full treatment from start to finish is covered. I feel it was a waste of money and misleading therefore would not go back.
