Not sure if this is an option, but many times, a group of us at my club will go in together and buy shells by the pallet. Many times, a distributor will give you a better price for huge volume. Sometimes, they'll even throw the pallet on the truck that delivers the clays to the club for no extra shipping charge. Other than catching sales at Dicks, Gander Mtn etc, good cheap ammo is hard to come by.
