"There really is a best time to do just about anything and everything, and that's especially true when it comes to buying things," writes Mark Di Vincenzo in his book, "Buy Ketchup in May and Fly at Noon."

If you're looking to cut back on expenses or score some deals, don't just consider where you're shopping - consider when you're shopping.
