IF you have an amazon Business account they have volume discounts:
e.g. buy 2 units = 3.62 each, or if buying 9 units = $2.41 each.
I ended up buying two of each through the business account.

(Originally tried buying more through my regular amazon account since I have some gift cards, but the price jumps to regular, i.e. they allow one, while on the business side there is no such restriction).

Enjoy. (…at least the lucky folks who manage to grab it before Amazon figures it out
