Duty-free means sold without tax in the shops beyond passport control. Duty-free shopping, a duty-free allowance, buy it duty-free.
The saving is on the tax rather than the price, so duty-free is not always cheaper than the high street. Every country sets a limit on how much you may bring in duty-free.
