Booze cruise
Booze cruise is a British colloquial term for a brief trip from Britain to France or Belgium with the intent of taking advantage of lower prices, and buying personal supplies of (especially) alcohol or tobacco in bulk quantities. Within limits, this is a legally acceptable process and should not be confused with smuggling.
