Join a Warehouse Club
When you think "bulk buying," you probably envision a warehouse club, with its sky-high shelves stocked with industrial-size bottles of laundry detergent, enormous tubs of mayonnaise and 36-roll packs of toilet paper. Yes, there are amazing deals -- especially on dairy, meat, alcohol, prescription medications and electronics -- but at the same time, don't let a good deal trump common sense. If you have a large family, you might be able to use a 12-pack of salsa. If you live alone, probably not.
