best site to buy ready made CDS in the USA?

Hi...thanks everyone for all this important info.  I purchased from waterpureworld but and they really have terrible customer service.  Any other sites that sells QUALITY products?  CDS, MMS, DMSO.  This stuff is so inexpensive that I really want to try to get the best quality I can.  thanks again.
 

Have you tried KVlab.com ?

i will if you recommend it

I have known Steve Pardee, owner of KVlab, for years. Many people are happy with their purchases. 

KVlab is my only supplier for MMS and CDS for years. They are very good.
