Good money saving tips? Anymore you can think of?

In the grocery store, I buy beef bones labelled dog food as they are cheaper and cook beef stew. I buy day old vegetables, bread, and fruit and buy mince for cats and cat tuna to make meals out of. I find this saves money. I catch rats and pull their tails off, and crumb them for my dog Rosie. She loves it. I use balloons as condoms, they seem to work the same and are cheaper, I make my own soap and shampoo out of things found in the garden and around the house. Anymore you can think of?
