Here's a list of what I buy, from whom, and how much $:
Potassium Citrate, The Vitamin Shoppe, $4.99
Vitality Coldwater Omega-3, Melaleuca, $14.99
Vitality Multivitamin & Mineral, Melaleuca, $16.99
Vitality Calcium Complete, Melaleuca, $9.99
(If I order the multi and calcium as a bundle, the price is $19.99.)
After comparing to the IP brand, these are
close to exactly the same.
If you're not familiar with Melaleuca, the full name is "Melaleuca the Wellness Company." They're based out of Idaho, it's membership driven, and sells pretty much worldwide. However, non-members can purchase, just at a higher price. What I pay is the membership price here in the US.
I hope this helps.
