This is best evidenced in the differences between the items available in the first Stores encountered in Dead Space and Dead Space 2, and the availability of the Pulse Rifle product.

In addition to schematics, Stores also appear to be keyed to the wants and concerns of local authority. This adds a layer of safety in the redundancy of vital information. Once downloaded to one Store, the device associated with the schematic is 'unlocked' in any Store, so it's also likely that the information stored upon them are both copied onto the RIG and the Store network. Schematics, true to name, are likely to contain device specifications in case of a failure in the central fabrication database. There is always a certain set of basic survival and work-related products associated with each RIG, but the selection can be expanded upon with the application of schematics. The assortment of items available to a user appears to be entirely dependent upon which designs to an item is associated with his or her RIG. The Store also has a 'safe' feature which can assure users specific items without credit transfer provided that they 'put something into the safe,' e.g.: they surrender any items to the Store for dis-assembly and possible recycling into other products for other users with the promise that the initial user can get their items back elsewhere.

In order to regulate and record resource usage, the Store employs a non-fluctuating credit system tied into a user's RIG. Utilizing on-site fabrication technology, Stores make use of stored amounts of pre-mixed, refined raw materials, plastics, metals, and composites to quickly create and dispense a set of pre-programmed products ranging from tools and toys, to weapons and ammunition.
