I have about 40-50 boxes of Remington Hevi-Shot. This is the "premium" non-toxic stuff comes 10 rounds/box. This is Remington Hevi-Shot NOT Remington HD! These are from a couple of years ago when Remington and Hevi-Shot were still teamed up.

12 gauge 3" #6 Remington Hevi-Shot. $175 per 10 boxes shipped.
10 gauge 3.5" #6 Remington Hevi-Shot. $160 per 10 boxes shipped.
