Remember with prices , smiling helps a lot, so does your knowledge. Ask the butcher a price for a case of sides. If Swifts that is 6 sides. I assume now most packers will use 6 as a case quantity.
Then ask a case price, and a single side, and a trimmed side. If you give him the three options he'll hit high on the trimmed, low and the case.
At this point you get your wife or girlfriends to flash those pearly whites at him again (don't let your wife find out you brought your girlfriend!) Then ask if the butcher would consider holding the case in his reefer and allowing you to pull one a week for six weeks. Actually I do two every two weeks but it averages the same.
Then after that first batch, take that butcher a piece and give to him. Ask advise, opinion, etc etc etc.... Get him on your side. If you are successful ask what he'd want to slice and wrap? Maybe a piece of macon would help with all that work...... Hmmmm.....
A good butcher is as great as a good barber, banker, doctor, accountant, lawyer, or dentist ( although not sure there's ever a good lawyer or dentist).
