First consideration for us is always food miles/environmental concerns. Canned food just does my head in when it comes to that - raw material mined in WA, shipped to Japan for pressing, back to Oz for being made into cans, then to wherever it's going to be filled, then back to Oz for sale. So, do you buy the organic beans that have come from Italy, or the non-organic ones that haven't travelled so far??? Can't handle it, so generally don't buy cans.

Next for us is the ethical concern; fair trade (free trade is actually the opposite!) or organic or drought-tolerant, or whatever.

Then we look at the packaging, and the sustainability level of that - paper/aluminium over plastic, large quantities over small, and never ever anything individually wrapped.

Price comes in pretty late into the equation. If something's on special we might buy a few.

Then we chuck it all on the bike trailer and ride home!
