st Louis Ball Bowler Co sells these on there website for $10 each. google st louis ball bowler co However, when I attempted to place an order for 10 of these, shipping costs were $47 and change. and YES, I bailed on placing an order. Not in my lifetime will I be paying $47 for shipping charges that at most weighs a few ounces.
Hopefully, at some point in the future shipping costs will become a tad more reasonable.
