As much as possible stock up on certain ingredients when they are on sale. You can freeze butter which is expensive so get extra when you see a good price. I buy shelf stable milk (in juice box type containers) this way I don't buy milk for it to go bad. Sugar and flour also last a long time. Invest in good quality baking pans and equipment because they last forever and will always give you a good result. Be creative! Have fun! Good luck!
