Yeah, home depot is a tricky case. They have a huge array of products, and in my experience when you cant find something you need to search beyond the store you're in....so the database you need access to isn't exactly small. Makes a practical offline experience tricky.
Home depots website sucks anyway, slow, clunky, terrible touch space, and the search is awful.
Aside, they should ad cell repeaters inside to fix all this.
