I know people probably don't believe this but I am trying to keep the cost down on these things. So, higher volume helps keep the price down. That being said, I wouldn't mind ordering some pipe ones. Who would be interested in a pipe insert? i.e., how many can I buy and not get stuck with them for years. I'm aiming to sell these as soon as possible. I've got some other good swag ideas I want to plow this money back into.
