Replacement lid for collection cup - BH-2000

Hi, I see you can buy a replacement cup, but it doesn't include the lid. Is there a way to get a replacement lid? Mine is slightly warped, it curves up just a little bit. Enough that it doesn't sit flush on the cup and is able to rattle around sometimes, making a pretty annoying sound around the tank until I slide it to one side or another to stop it. I was just about to place my order for an AQ-2000S, if anyone feels like throwing a lid in that shipment I wouldn't complain ;)

Thanks,
Andres
