I will have to put the under gravel filters in a thin, long box to ship. I don't think it will be very much to ship them but I have way too many free shipping items right now plus I am having to pay out shipping for my orders and I just can't afford to ship out something that can't fit into a small container or envelope at this time. Sorry.
Yes, there is a chance. It depends on how high the bid goes. The magnetic cleaner is heavy and expensive so I will have to get enough credits to make free shipping offset the cost.
