send (something) COD
To dispatch something to a recipient who must pay for it upon delivery. "COD" is an initialism of "cash/collect on delivery." All our products are sent COD, so please be sure to have cash ready when your item arrives. I asked them to send the furniture COD so I could inspect it before handing over any money.
