| /datum/req_contract/special | Contracts for utilisation by the special order event. These are distinguished by the requisition being sent physically, either standalone or in a crate with stuff. They are not inspected by the requisitions handler, and do not receive the screwup protection that is afforded to regular contracts. They do not appear in the general market. |

| /datum/rc_entry/item | Basic item entry. Use for items that can't stack, and whose properties outside of path aren't relevant. |
