Even buying the really good beans, you'll never break even financially with making your own coffee at home. You get like 20 16oz tumblers out of a $10-15 bag, so less than 50 cents a serving. You're looking at least double that getting powdered pre-workout, which doesn't even dissolve all that well, making adding it to a sodastream or something not really feasible, so you'd still have to shaker bottle it. If the only thing you care about is the caffeine, and not the experience, than pills are by far the most economic option at pennies per 200mg.
