Means of selling unwanted items (3,4,4)

Ross

I believe the answer is:

car boot sale

(Other definitions for car boot sale that I've seen before include "Fair" , "field event?" , "Event involving trade conducted from the back of one's vehicle" , "place for bargains?" , "Vending of second-hand goods from private vehicles" .)

I've seen this clue in The Mirror.
