Even Walmart and DIY box stores have adopted parts of Amazon approach, though the lack of depth in the back office IT does compare.
Many offer the web purchase with store pick-up. That service seems to vary according to store manager whims. If there is a pick up zone, all’s well, if the store doen’t make the pick in time the customer loses the advantage.
Lowe’s web site includes bay and aisle location to speed up locating items quickly, however each store varies as to accuracy of inventory feedback to data bases, so often the items are not there or returned to wrong position, or no longer in stock, small parts are the most affected.
IIRC, Walmart web also has third party sources for some items.
All in all, Amazons competitors are finding that that backend support has developed and constantly refined has greater cost than the competitors imagined, costs that troubled stores can’t afford. They’re playing Little League ball against World Series Champs.
I go to the Lowe's one town over vs. the local Menards or Home Depot specifically for the reason above: I know walking in the door which aisle to go to and where what I'm looking for is supposed to be. Their inventory status via the web does leave something to be desired as you pointed out. There have been one or two occasions I went to Lowes only to discover what I wanted/needed was out of stock. If they could fix that, Lowe's would be golden.
