The stores can cast themselves as warehouses, print one copy and see if it sells either in-store, or online through Alibris. If yes, print 2, warehouse at 2 other stores (which can incidentally be "warehoused" on display shelves). If sold, print 4. If sold, print 8. O(n^2) up to some point then switch to linear or O(log(n)) growth. Eventually, your last run will print.
