Tips on cutting the grocery budget

So over the years I feel like I have read every single thing ever written on the subject of cutting the grocery bill. I was trying to think of all the tips today and thought I would write them all down to help myself (and anyone else who is curious) remember them all.

*Once a month shopping
*Buy in bulk
*Shop sales flyers
*Coupon on items you will use
*Grow you own fruit/veg
*Can/freeze your home grown produce
*Menu plan
*Join a CSA
* Cut out paper products (papertowels, etc.)
*Make your own cleaning products

I am already planning our garden for this spring and researching local CSA's
