Interesting, even though I told her I was with the group by, she told me 5 units.

Quote from Chloe:
If you buy only 3, then I’ll have to wait for somebody else from the group to place an order of at least 3 units, since you are the first one to claim that you are from the group buy.

I suppose I could be reading that wrong, but she required at least 5 units to a single address.
