What I've noticed is many retailers only carry one or two name brands and flank them with their store brands of which they usually have three tiers.
So for example you only find Ryobi tools at the Home Depot but Craftsman and Black+Decker are exclusive to Lowes. Grocery stores do similar exclusivity with certain brands, Sargento's cheese comes to mind.
