Well, MMS is close-ish. They are in UT. Their everyday prices are a tad more than some places, but without having to ship it clear cross country, total per unit cost is sometimes cheaper. And the "free" shipping is kind of a misnomer with WSP, because they add the shipping into their product cost, but sometimes even with them doing that, it will come out cheaper depending on the qty bought. The research to get the best deal possible (and all the math) can be daunting, but with significant savings, it can be so worth it. Good on you for doing it.
