See a chain or big box store selling the same item as you have in your store? Lose it from your cases.
WHY? First, it’s likely they are going to undercut you on price sooner or later and that is an area where you can’t compete. Perhaps more importantly, it undermines your promise of exclusivity to customers.
HOW? Every few months, drop by your corporate competitors to see what they are offering. Urge your staff to keep an eye out as well.
