I needed to get 800 feet of 1" waterline. My normal plumbing supplier, who is regularly noticeably cheaper than the box stores, wanted 94 cents a foot. I called a supplier in Virginia, and they wanted $1.24.
I looked online at Home Depot, and Lowes, to find that Lowes hadn't raised their prices yet. Their price is 64 cents a foot, for good made in the USA pipe in 20 foot lengths, so I went ahead, and ordered it, for pickup, online. The 20 foot lengths, which was what I was looking for, have a bell end on one end, that doesn't require separate coupling fittings.
If Black Polyethylene had been half the cost of PVC, which it normally is, I would have used that. It was not available anywhere for less than this current Lowes price on Schedule 40 PVC.
Anyway, if you have a need in the near future, I'd go ahead, and get it now.
