A sorting system is disclosed, for example for mail items, wherein in the disclosed system, a circulating storage system 6 can receive items from an inlet 8, and deposit them in an appropriate output receptacle 12 which has been allocated to items in a particular group. For example, the items can be sorted by destination, and each output receptacle can be allocated to a particular destination. In the event that the destination of an item has no output receptacle allocated thereto, the system controller can determine whether to allocate a receptacle, or whether to recirculate the item within the circulating storage system. This possibility allows items to be grouped together within the system, until there are sufficient items for a particular destination to allow them to be handled efficiently, and in particular allows the allocation of output receptacles to destinations to be controlled efficiently. The sorting system may be provided with two or more carousels, the items being transferred from the first to the second carousel as desired.
