This site is absolutely uncomparable to groupon site, especially their customer services. There is risk you'll just lose your money because of their irresponsible process. We purchased the O Spa Landon voucher, but tried many times and always encounter errors when applying the voucher during the transaction. Emailed buywithme site, and were told to wait a week to use the voucher because the merchant site had technical problem…waited more than a week, still not working, yet this time even worse, it said the voucher had been used! Emailed again buywithme, but this time NO response from them at all! Very frustrating and dishonest business.
