Yep we meal plan. Shop at the Victoria Market perhaps once every 6wks for our meat. I grocery and fruit n veg shop once a week and top up on fruit on a Monday.
We also give ourself what we like to call 'rations'. So that means we each get a certain amount per fortnight and cannot go to the bank or use our cards in that fortnight, we have to ask each other if we run out, that stopped me over spending
I get our money out on the day DH get's paid and that's it. No more going to the bank or using the card (petrol excluded).
We put money in account for our morgatge and another account for our bills. It works well for us.
