In the spirit of something or other since I started at the shop we've moved over to shopping twice a week. Once for the main stuff and once for me to buy stuff from other shops and for the dreaded "top up". It's so annoying!
Although it's been surprisingly good for the budget, it feels as though I'm always shopping and we always need things. So we're going back to once a week shopping, other than a trip to the greengrocer for rabbit greens on my way to the charity shop.
The main thing I dislike about it is that we never run out of anything, as soon as we run low on something I add it to the list to buy on Tuesday, or it goes on the main list for Friday, depending on when we run out. Where's the fun in that? It's good for us to have to make do, to use up the bits from the fridge and the things that have been hanging around in the freezer. There's satisfaction in eating something that's been cobbled together and more joy in adding something to the list when we've not had it for a while.
