I'm remodeling a house and I end up having to go to one of three HD stores that are each about five miles from the house. Each is in a slightly different area demographically and thus has a different selection of stuff, and each has a very different layout.
Their listing of stock and aisle/bin makes it easy to find what I need, but the site is so awful on mobile that I'll often look things up at home on a full PC, write down locations, then go.
On mobile I've seen the layout shift all over, the search break if I touch something or scroll after I submit a query, checking the "in stock items" box sometimes breaks my session. It's awful.
