Because of the number of add-on added to pledge, the planned order will be broken, we will ship by wave order (1,2,3) AND completion of the pledge manager.
We build these in house, we are planning one shipment each week starting in the last week of September. (Latest new add-ons will add a week or so for the preparation for mass production, plus we had not planned a pledges manager at the start of the campaign)
We've splitted the pledges monthly, only 130 sets can be brought for September. Since our capacity right now is 300 sets per month, this should let us the time to receive raw materials and packaging boxes. But I agree that September could be a close call. I plan to add new pledges in November and December to spread out the production somewhat evenly once the starting pledge are sold-out.
