I ordered 5 pounds of 100% Optimum today from amazon.com for $38. Thanks to JCane for telling about it there!
I am holding off on ordering the Jack3d because I went to a store here in Mooresville to buy some protein bars and the guy there gave me a ton of samples for pre-workout drinks. He gave me at least a month's worth. N.O. Ignite, 1.M.R, Bullnox Androrush, and Extreme Shock. I have never used anything before but I am not sensitive to caffeine at all so I shall see.
