This isn’t a pun, but it’s close:
A woman walks into a hardware store for some latches for her gate. As she waits for the clerk to ring up the purchase she spots a deluxe coffee maker on the shelf behind him and asks how much it is. He tells her the price, and she decides it’s too much. The clerk begins to ring up the latches and says “Do you wanna screw for these latches?” and she says “No, but I will for the coffee pot.”
LOL
