This is because the customers at Home Depot and Lowe's are primarily muggles. The wizards will pop in if they need something and it's convenient, but by and large they buy at wizard stores that stock the full range of fittings. Said wizard stores sometimes have a handwritten sign taped up on the wall behind the counter dating back to the Carter administration that reads "Those in the trade will be served first"[0]. Your reward for being a wizard is having competent help at the store, and the fittings haven't been randomly distributed among the bins by a million prior muggles. Electrician wizards similarly work with electrical supply stores, not Home Depot if they can avoid it. Carpenter wizards cross over a little more, but they generally prefer to work with lumber yards that deliver[1] and have halfway decent lumber[2]. [0] Yes, literally. [1] I believe the box stores do to, but they charge handsomely because they don't really want to. [2] 2x3's are crap everywhere, but the quality on anything bigger goes up immensely at a real lumberyard.
