Various embodiments of a system and method for message-based purchasing are described. The system and method for message-based purchasing may include a message-based purchase service configured to determine that a selection has been performed through a network-based interface. Such selection may be indicative of one or more items offered for sale via the network-based interface. The message-based purchase service may be configured to, in response to the selection of one or more items, send to a communication device, a message indicating a code corresponding to the selection. The message-based purchase service may receive from the communication device through a communication channel that does not include the network-based interface, a message including the code. The message-based purchase service may be configured to, in response to determining that the message received from the communication device includes the code, generate a purchase request for the one or more previously selected items.
