Cost Cutting

Business is booming these days. The internet cafe that I own is now selling soda pops, and several other snacks along with a game cards cell phone loads and other prepaid cards. Now, I wonder if I can lessen my expenses like electric, water, and internet bills. What really ticks me off is the price of my printed receipts. I have mine done on a printing press which which costs a lot and some times, when I stack too much, it gets eaten by rats or other insects. I wonder if receipt printers, although costs a lot, would minimize my operating expenses with regards to receipt.
