A friendship store (Chinese: 友谊商店) is a state-run store in the People's Republic of China (PRC), which initially sold exclusively to foreign visitors and tourists, diplomats, and government officials, but now has no restrictions on customers.

Tuzex was a series of state-run shops in Czechoslovakia from 1957 to 1992 which did not accept normal Czechoslovak koruna currency but only vouchers (bony) which could be purchased from banks using foreign currency. They supplied luxury items: local goods in short supply and in particular foreign goods. The Tuzex vouchers were effectively an unofficial parallel currency.
