The only thing we really look at when buying products is animal welfare. Tend to only buy free range and organic meats/eggs. Dolphin-free tuna, etc, etc.
EDIT: Though, I will say this, I am thoroughly impressed by Tesco's corporate responsibility pledges (people from Cali/Ariz/Nev will know them as Fresh 'n' Easy) - they seem to be very environmentally friendly. Make no mistake, though, they only do it because they think (and are probably right) that it's more cost-effective in the long run to do so.
