Proposed Business Model
Was not aware that your store offered the Quali-C. Was purchasing from Amazon via the GMO jars for a long time. We will continue to purchase from you in the future. We load our own capsules because we want non-Chinese product. Sorry but we just don’t trust them. Many don’t. Just check out the “hundreds” of individuals asking about product source on Amazon about source of C. It is a widespread concern. They don’t want the Chinese product either. There is only one company selling USA made C and that is United C on Amazon. We purchased many a bottle before we started to load our own capsules to save money. Proposed “Pie in the Sky” business model for your store. Purchase a capsule loading machine and load C with Quali C and offer for sale. We like your other products also due to quality of source material!

Reliable Service, Excellent Product Quality
My initial order never arrived and they sent out a new order promptly. The Vitamin C was powdery and packed in an airtight bag. The Life Giving Store seems like a reputable vendor.
