one of those "pick-ups with a freezer in the bed"  made a cold call at the house some years ago.
He had  what must of been a trainee with him
i was bored so i let them in to hear their schtick 
guess he didn't figure on me getting the calculator out  to figure the price pr "pound" of the meat he was slinging.
it actually pi$$ed him off  
 
 
I'd venture a guess there's a fair amount of profit in it (donno what percentage the street salesman makes) but the price pr pound for their low quality  garbage  meat was as much and more as top quality butcher cut fresh meats ..when calculated by the "pound" 
the "package" deals are a complete rip-off .
They give you mostly hamburger and chicken lEgz.
That's when the dude got pissed off about my calculator , cause the trainee listened intently as I showed how  
quality prime cuts of meat could be bought locally for $XX pr pound but  the bulk of their   "package deal"  was hamburger and 49 cent a pnd chicken legs.
by weight, it was 3 to 4 times as much 
so i'm sure there's plenty profit to con  out of the gullible rubes they prey on
..L.T.A.
