For Sale Win. AA12 Red ((Older Style One Piece Compression Formed Hulls.)) $.05 apiece plus shipping. I use USPO Parcel Post it is the cheapest. Minimum amount shipped is 1000. All that are sold on Ebay are the new style two piece hulls. They sell them cheap and charge you a fortune for shipping them to make a profit. After my current supply is gone, I don't know when I can get more. Guys that have them are keeping them because of being hard to find. Shipping depends on your Zip Code.
