Sept Challenge

I read a blog about a Sept spending challenge and I will participate. The idea is you spend the next 2 weeks organize and planning and as of Sept you try as long as you can not to purchase anything. Now there are some things you are allowed to purchase such as

gas for car
milk
fresh veggies
meds or things of emergent nature
planned activities such as church function, preschool payment or weekly childcare

You can also buy things if you plan your coupons and sales so they are free!

So I will be stocking up with coupons and planning, and will see if I can make it a week or 2 without non necessary shopping! Anyone else want to try?
