Usually licensed merchants will go 2-3 times over costs. Working on the 'good ol' boy' standard and thinking about how valuable your time is. Figure from 50% of costs on up. That'll give ya some spending / upgrading money.
On edit: To clarify - Cost of all materials, meat, etc plus mark up of 50% of that cost on up.
$9.95/lb ... if I would've charged that for the 8# butt I'm doing for someone I would've made a killer profit!! I'm a sucker for generosity and for this first "bought" smoke, charged $25. Now that I've seen some of the prices posted here, will definitely have to up the ante!
