That's not my experience. Last month I tried to buy a specific vacuum cleaner at Lowes. Online said it's in stock. It wasn't. Another nearby Lowes said it was in stock. It wasn't. I finally got smart enough to call the third Lowes instead of driving there. The guy said "it shows as in stock but let me check". They know. It wasn't.

This has been roughly par for the course in my experience, and not particularly with Lowes.
