It's actually not that easy to save money on mixing your own. It's great
if you make up non-commerical stuff. Or if you need non-standard sizes. Or
for making up stuff already diluted. But it's easier to buy the commerical
stuff and unless you're buying the small packages you might be saving money.
Or if you're throwing out a bunch of stuff because it's gone old.

Not saying you can't save money with mix your own but it's not the
reason I'd do it. Just buying the big package will save you alot more money
usually.
