AmafanHey Amafan,
Congrats on your first drop! As soon as it ends we total up the number of units purchased through the group buy and we order that many from the product's manufacturer. The manufacturer sends the units to us all at once in a single shipment. Within 48 hours of their arrival at Massdrop's fulfillment center, they're sent out again as everyone's individual orders.
