The only thing we really "Waste" money on is casino night. Hubby and I go about once a month, and spend $100-$150.
Otherwise, I consider the following not wasteful, but still expensive:
I buy 75-100 bags of corn per year , and I feed the deer on my property year round. (yes it is legal here)
I buy higher quality pet food (Taste of the Wild) for the dog and cats. Roughly $45/bag I also buy canned food for kitty breakfasts. $15/month
My truck payment. But hey a girl has to have her truck! 2009 F-150
Extra treats at the grocery store for the chickens! (Cherry tomatoes, kale, cabbage) (this will come out of my garden this year)
Lumber to build new chicken coop and run this spring.
This year I will be spending money to start a garden. But I do not consider this wasteful, because it will feed my family. Same goes for spending money on hunting licenses.
