You may think that items are identical to what you find at a dealer’s store; however, in many cases, what looks to be the same really isn’t. Whenever possible, “box stores” dictate to it’s vendors what it wants to sell an item for. The vendor must then find a way to make it happen. While it may not always be visible to the naked eye, manufacturers cheapen products to make them less expensive. Keep in mind – everyone has a profit margin to maintain if they want to stay in business.
