If this is a Group Buy, why are the savings of the group buy not being passed on to buyers?
Who is keeping the bulk savings when you place the order of 750+ devices?
I don't understand as I the idea of the group buy is to buy in bulk and get a discount for everyone?
For example you said you have ordered a very large batch, that means that you could price the devices at .41 and take a handling fee per device / per order.
