We don't have much money - our food (and cleaning stuff etc but NOT wine!) budget for a month is strictly £200 (ok, there are only two of us and a cat) but everything we eat is organic (not grown ourselves yet as this is our first year with a patch for ages) local and if not, fairtrade where at all possible. I can honestly say that unless it is a real emergency, I don't shop at supermarkets.
I get snotty looks from certain family, when they are at ours and the Riverford meat box turns up. It is well known that we have no money, and I think they feel like an organic veg box is a luxury we can't afford. But we cook from scratch and plan meals roughly for the month and order in bulk from ethical online suppliers, so I very much doubt we spend more than she does, shopping in Waitrose!

Something in the film really hit home - when an independant farmer described how people baulk at paying $3 for a dozen eggs - and moan about it with a 75c can of coke in their hands. He also questioned why cheap is always best with food - when nobody wants to buy the cheapest car on the market.
Oops, ranting yet again....sorry.
