$10/box is probably what you're going to pay.

I ordered in a case of Fiocchi 7.5 target 1oz. at around $11/box after shipping.

Then I found some Super-X game loads at cabelas/ass pro (ship to store only) for $95 total. I'm not sure they'll be here in time for dove hunting as we're going the Sat before opener for p-dogs and Eurasian dove.
