I thought the same thing: about spending $150 or so on BP. Cash flow and all that. But then, I thought, it doesn't go bad and it's not like I don't use it; after all, I did run out, didn't I?
I waited and did the old "set some $ aside" and shot subs until I could order.
Even with the Hazmat fee, BP is less expensive than any of the subs.
