To go a little off topic, what bothers me about groups like this, whole foods, and others, is the amount of needless packaging. For me, I buy all of my animal proteins at one of three butchers and most of my veg and bread at one of two farm markets (or a farm itself). At least around Vancouver, this is not difficult process to emulate.
These groups seem to justify their packaging by saying it's recyclable -- but that's just not good enough.
Whenever possible I try to get friends into the butcher / farm market system and away from those overly priced supermarkets. For me, I can make a fairly substantial dinner, braised chicken with plenty of veg in a madras curry sauce on rice with naan bread (from a local indian restaurant since its $2) for about $12 total. The main expense is the chicken, but even that comes to about $7 or so. This meal can easily feed four adults.
Getting these ingredients from a typical supermarket (not Whole Foods) would easily surpass $30.
