Really? I shop at Lowe's a lot. I often find isle numbers like BW. I assume that means something like "Back Wall" but, nope. There is no map that I'm aware of and no indication where it might be on an isle (save a bay number, which is almost always wrong). It is "good enough" to get me in the vicinity on some products but not others. A store map showing me where isle BW is would be a great addition.

At least in my local stores, things have frequently been rearranged to be in a different location and the online inventory didn’t get updated. So I have to find an associate and ask anyway. Home Depot seems to be much better at it.
