면 팔다

if X, sell it

A conditional plus 팔다, to sell. Some lines are shopkeeping: they are probably selling it outside, it is easier to sell if you price it below that, if people come to eat we sell to them. Others are trading talk, where the rule of thumb about selling when it goes up and buying when it falls appears twice. 팔다 is selling something; 팔리다 is the goods being sold.

Register: mixed; retail and market talk
