I called the butcher at Sam's that I normally work with and he can sell me Eye of Round for $2.79/lb when buying by the case. (60 to 80 lb cases). That helps to bring my cost down considerably. I also found a wholesle distributor of vacuum seal bags where I can get the quart-sized bags for 20 cents a piece shipped (3.5 mil bags).
For those of you that sell jerky are you required to use a certified scale since you sell by the pound?
