For meal planning, http://www.kraftcanada.com (for those in Canada) or http://www.kraftfoods.com(in the U.S.) has some great tools that help with meal planning that my daughter can help with, and with the online meal planning it also does my shopping list for me… I dont forget any ingredients that way.

I have found a great way to save on cleaning supplies. I now make my own. Vinegar is a chemical free anti-bacterial agent and citrus will cut through kitchen grease and make the vinegar smell better. I simply save my orange, grapefruit, lemon and lime peels in the fridge in a large ziplock bag when full I put them in a large jar, top the jar up with vinegar and let sit for 4 weeks. After 4 weeks I pour the vinegar into a spray bottle and voilla homemade, chemical free, cheap kitchen cleaner. Cost is minimal as I’m eating the fruit anyhow, and a couple of litres of vinegar is only a couple of bucks, I’m no longer paying 5$+ for a bottle of cleanser.
If you dont like the citrus you can substitute with lavender spriggs.

Toilet cleaner is expensive as well, I now use 1/2 cup of vingar and 2TBSP of baking soda. This both cleans and disinfects for very little money.

Don’t expect to buy everything in one place. Go to the butcher for meat, fishmonger for fish, etc.

Here the “supermarket” run a dividend scheme (it’s a co-op), and they double up on Tues/Weds, so I buy all cleaning products, other boxed/canned/dried goods on those days – otherwise its fresh all the way baby!
