Starter tool kits
If you are comparing 2 exact same model numbers, shouldn't matter where you buy them. Big Box stores are DESPERATE for more contractor business, so they are constantly pushing their vendors for high qualitity and lower prices. IMO, most of the "lower qualitity at big box stores" stories are just rumors put out there to discredit Depot's and Lowes since they have deeply wounded the local supply houses
Those who can, do...
