wow, how come your price so cheap ga? I also use this brand ( diaxxxx), over 1 year, but i knew that there is no membership of that company. Also no any discount for customer...even bulk order for company also standard price wor, so, what's going on? Anyway, even different positive and negative opinion of this brand, i cannot totally trust TV advertising, but i really found my son and my daughter's health become strong.....especially my son've got asthma ( may be wrong spelling)....but now, better than before, my skin problem also. So, ok lar. It's worth to try.
