The cheapest way to buy MSM in bulk is in powder form. However it is not terribly economical to buy small quantities of the powder. The lowest price we found for 100g - which frankly isn't very much for those who want to take it in robust dosages - was £10.50 plus shipping! That's equivalent to around £90 for 2lbs before shipping. In deciding to sell MSM powder, we decided there wasn't any point, unless we could sell do it at half of that price when you bear in mind our shipping charge is 1p. This meant we would need to sell it in quite a large size.
