Ppl are having GBs like 5/$30 shipped. I pm youFound a Hospira Bac water source that doesn't require a script or the purchase of peptides... Not exactly cheap, but it's a source... $17 for 30ml, plus shipping. They have bulk pricing, but it's only like 5% discount.
And based on the website name, I'm not sure how much easier it could have been, but took me a while to find it, for some reason.
