expression
it's a steal!; take it away, thief
A playful vendor's cry at market stalls, implying the price is so low it's practically giving it away. Literally 'take it away, thief'.
「持ってけドロボー！」と八百屋のおじさんが叫んだ。
"It's a steal!" shouted the greengrocer.
この値段なら持ってけドロボーだよ。
At this price, it's a steal.
From 持っていけ (take away) + 泥棒 (thief), literally 'take it away, thief'. The phrase is used humorously by vendors to emphasize a bargain.
