Just another li'l data point about our favorite store to mock, bash, deride and insult here. Something actually in their favor for a change.
I need an ordinary duplex outlet for a job. Went to OSH (Orchard Supply), one of the places I prefer over HD; the want something like $3 for the cheapest one. So it's off to HD for this, where I know they sell those suckers for less than a buck. (They must buy them in lots of a million or so. Surprised they don't have their own house brand.)
Point being, yes, I hate Home Despot, but they're clearly cheaper on some things. (Not all; OSH is actually cheaper on many items.) So the trick is to buy selectively.
Oh, and their return policy is pretty sweet. At least from my experience, they'll take back practically anything, no questions asked. (But then OSH has a similar policy.)
