This logically breaks down 100%.

No company on the planet would make inferior products just to sell them at home Depot. This would make their better products just perform worse. As you would see a failure rate of tools increase dramatically from just one shop (which is honestly the most popular) giving them a bad record. On top of that even if you consider they 'bin' these devices, they would still not logically want the bad ones at one store while also selling the good ones at other stored. It goes back to the same 'Image' problem.
