When you buy 10 or more of the same game in a single order, or use the Bulk Order Fulfillment system, those orders go into the bulk queue. The bulk queue works like our other queues in that it is first in first out. However, it is the slowest of the queues because we're processing all the large orders through it, so it can take several weeks to go through the bulk queue even though it only takes several days to go through the normal queue.
We implemented the bulk queue so that our normal queue runs more efficiently. We used to intermix them, which could create delays. This new way ensures that our entire production process is moving along more efficiently.
