I feel your pain. I placed 2 orders with them and both times shipping was far more than the order.
I sent them an email asking if they could ship via usps, but no answer.
They sell quality parts, but shipping costs stops me from ordering any more.
I think they are a small husband and wife operation, I meet them at the gun show in Raleigh years ago.
Del-Ton ship USPS and you got my business
