Yeah 40 vials is a bit much for almost any purpose. Would be better to require a 2 kit, $200, or even $250 minimum, allowing other full priced products from the international warehouse (assuming that's where it's coming from) to be added to the order to reach the minimum $ amount. Like a "loss leader" store discount requiring a minimum purchase of other goods.
Then again building up a buffer supply may not make much sense.
We have a new self appointed mod here at MESO, so I'll defer to his judgement on this one. What do you say,
@Lexington ?
