Partial list and by The Hill, so take it with a grain of salt.
What I found most interesting was that TJ Maxx, Marshalls, and Macys didn't have a "no guns" policy. Given their clientele, you would think they would do so almost from a "good business" (for profits) practice.
I always carry in Costco. I've never seen a "no firearms" sign on the door of any Costco. Concealed is concealed, by I know that I have printed and/or "let my slip show" on numerous occasions. I'll continue carrying there until they throw me out.
I see they apparently didn't ask Home Depot, and Lowes didn't respond. I'd be disappointed if either of them had a no guns policy.
