Abstract: Storage apparatus having a plurality of lockable storage compartments, wherein at least some of the storage compartments are temperature controlled. Storage compartment temperature information, SCTI, indicative of a locker temperature category of each storage compartment is obtained. Order information associated with an order of a plurality of items for storage is received, including desired temperature information, DTI, associated with the items, and temperature tolerance information, TTI, associated with the items. The TTI indicates a thermal resilience of the items. In dependence on the SCTI and the DTI, a capacity of the plurality of lockable storage compartments for receipt of the order is identified, corresponding to the DTI for the associated items. A subset of the plurality of lockable storage compartments is determined for storage of the items, in dependence on the identified capacity, DTI and TTI. The subset of lockable storage compartments is unlocked responsive to arrival of the order.
