I don't know who you are competing against.
The stuff in the supermarkets is almsot always less than a pound.
Heck even the Shoprite (store brand) OJ just got put into 59 oz. cartons instead of 1/2 gal.
Back to coffee. The local shop sells Free trade coffee by the pound. They used to also sell by half pound (measured by volume) if you asked, but mostly now its obviously prebagged. Up the street the co-op sells by bulk so thats different.
