was chatting to mieow last night about how we used to do food shopping really cheaply, but as we have started going to tesco again rather than farm foods, lidl etc our bills have rocketed. but how do we go back into it? we're not struggling atm, so part of me says stop being silly, but i would like to be able to save up to take the kids to eurodisney at xmas 2007, and this seems a good way to start.
