How low can you go challenge?

A few weeks back, and undoubtedly at other times, there have been posts and threads started about doing SW on a budget and at the time I suggested a challenge to see just how cheap we could make SW.

We all know that the plans in the mag can be expensive to follow verbatim, but the repetition of 'favourite budget meals' and 'cheap SW' threads make me wonder if there's some ground to be made in having a month long challenge to see just how cheap we could make it?

Thinking it over I thought a month would be better than a week as it's more representative of most peoples budgets/paydays and the plan I was thinking of doing was Extra Easy.

So starting from tomorrow and my shopping gets done then, I'm going to give this a good run for a month, it's the run up to Christmas (only 7 weeks to go) and I want to be back on track, hopefully shifting a stone by Christmas.

So keeping your meals varied i.e no repetition of pasta and veg 7 nights in a row and trying to have something different most nights - How low can you go?

What would you like to see incorporated?
What rules would you like to see?
Would you prefer a seperate blog for this?
Is this something you would be interested in seeing?

I'd be interested in seeing what people could do, not so sure I'd be good at sticking to it though amybe for a week but not a month.
Could depend on exactly what the guidelines etc for the challenge could be I suppose. It would depend what already had in etc like today I am going to go costco and stock up on some meats etc for the next few weeks so how would I include them in the menu for the budget time?
Would be a good time of year to do it though cut some extra costs so have some extra pennies for christmas!
