I agree with the hubber who says - write down every single penny spent. That way you can 'track' your money.
Grow your own veg, fruit, keep hens, ducks, poultry - even in a small space. By not going to the store for these items you will make better use of your time, energy and ingredients.
Bake your own items - bread, cakes, pies etc. Everything homemade tastes better, so therefore, i believe, your needs are more satisfied.
Re-vamp old items into 'new' furniture, clothes, curtains, cushions. Get ideas from magazines, online.
Discard the credit card - use a debit card, if needed. you will feel the 'pain' of the immediacy of that money spent.
Buy as many items 'on sale' or 'reduced' as possible. Make a 'hobby' of it.
Look for the discounted items.
Ask for discount.
Look for the 'free' items. Make a hobby of it.
Swap unused items with friends, neighbors etc. for things you want. Make it a festive occasion.
Live on less. Make a philosophy of it.
