Careful with borg flooring. The local one had a sale on some
prefinished birch.

It had zero warranty on the finish, and I could make permanent
impressions in the wood just by running my fingernail across it.

I'm no cheerleader for BORGs, but over the summer, I bought genuine
Bruce, prefinished solid 3/4" oak flooring, with a 25 year residential
warranty, from Home Depot for $2.39 sq/ft.

My floor has exactly the same warranty as the same product selling at
twice the price elsewhere.

I'd be careful, but there are decent deals to be had.
