The prices are good for the most part, however, some items are way off beat. A remedy for $38.99 at Qi is for $16.99 at Ottway. Thats too much of a difference. Same with Quercetin AOR. $33.00 at Qi, $22 at other places. So, make sure you have shopped around before going there.
Besides, if you have a question, dont ask at Qi, they will give you an answer that you cannot understand. You want good customer service for the bucks you are spending, then this place does not have that. I spent over $200 and it was as if they did not give a damn. Every time.
