Abstract: A computer-based method for receiving purchase transaction data generated by a retailer system triggered by an identification device that is part of one or more reusable bags used by a user to carry goods purchased during the purchase transaction. The user is a student or student family member affiliated with a school or other community-based group. A reuse program server receives identification information provided by the identification device that signals the purchase transaction, updates reuse indicator information for the school; calculates a current savings to the school associated with the use of the reusable carrier; and transmits information indicating the current savings to a display device accessible to the user or to representatives of the school.

Abstract: A reusable packaging system includes a series of four bags, each designed to be reusable and capable of standing upright when in an open state. The bags are constructed so that they will fit in an open state within a shopping cart, and differ progressively in size so that they can be nested inside of each other for storage. The nested bags are then folded to form a compact, single package which can be easily transported by a user to a store for shopping.

Abstract: A closure system for a flexible bag. The flexible bag includes a plurality of panels defining an interior compartment of the bag, and a mouth portion for accessing the interior compartment of the bag. The closure system is implemented in two opposing panels of the plurality of panels. Specifically, each one of the two opposing panels further includes a first portion defining a handle and a second portion including an aperture. The first portion of each opposing panel is positioned at a top edge of the panel proximate to the mouth portion, and the second portion of each panel is positioned adjacent to and below the first portion. The handles of the two opposing panels are configured to be drawn together, inserted successively through each of the apertures, and then cinched in order to close the mouth portion of the bag.
