Editing Self-addressed stamped envelope (section)

==Alternatives==
In Japan, [[return postcard]]s are used for similar purposes.

SASEs cannot easily be used for international mail, since senders rarely have supplies of mint foreign stamps. Instead, [[international reply coupon]]s (IRCs) can be purchased at post offices, although they are no longer sold in some countries, including the United States.  Users of IRCs will often, as a courtesy, also send a self-addressed envelope to save the receiver the cost and time of buying and labeling an envelope.
