My Lowe's and Home Depot both have free Wifi. I use it all the time to use their app or site to find the location of items in store (obv. can't talk to humans).
Target (specifically mentioned by the parent) in my town also offers free WiFi.
Good luck with that. I tried unsuccessfully, to buy an item at both Lowes and Home Depot but nobody was able to determine where in the store the item was even when I pulled the information up on my phone.
Both the Lowe’s and Home Depot by me have the aisle/bay listed on their website. It’s usually super convenient, except for their numbering of end caps. That time it took a couple of tries until I found an employee who knew what was meant.
One of the Home Depot's in my area had broken Wifi for multiple months. You could connect, and go through the disclaimer, but nothing was reachable through it. Particularly annoying because the other store, which is about the same distance away, has working Wifi but horrible reception. Since I'm occasionally in each, I had to remember to forget the Home Depot Wifi and add it back in depending on when I wen tto different stores.
