If it feels like you're spending more and more on food every time you walk into a supermarket, you're not alone. It's almost as if everything costs multiples of $10 these days — a pound of cheese at the deli counter is around $10, a small bag of dog food is over $10, and paper towels and toilet paper can easily set you back $20. Want a few good steaks for dinner? Fork over $30, $40, or more.
