noun
Refers to something unexpectedly good obtained with little effort or cost, like a great deal or a stroke of luck.
この花瓶は百円だった。本当に儲け物だ。
This vase was only 100 yen. It's a real bargain.
雨が降ってきたが、ちょうど傘が落ちていた。儲

掘り出し物 emphasizes a rare, valuable find discovered by searching, while 儲け物 focuses on the lucky, profitable aspect of the acquisition.
お買い得 is a more common, everyday term for a good deal or value for money, often used in shopping contexts, whereas 儲け物 carries a stronger nuance of unexpected luck.
Compound of 儲け (もうけ, 'profit, gain') and 物 (もの, 'thing'). The exact historical derivation is uncertain, but the word has been used since at least the Edo period to mean a lucky or profitable acquisition.
