The IKEA kitchen sales event happens three to four times a year and runs for about six weeks. The discount can mean 15-20 percent off a kitchen purchase of $2,000 or more and applies to cabinets, appliances, countertops, lighting, and even drawer and pantry organizers—anything you need to design a new kitchen. All of this can translate into big savings, so we hit up IKEA insiders for their little known kitchen-sale secrets. Here’s how you can squeeze even bigger bucks out of the event—plus a trick to lock in your discount before (or even after!) a sale has ended.
