There was just this one thing that I needed and I couldn't find elsewhere. And while I didn't want to shop at Lowe's, it popped up on my horizon and knew that if someone else didn't have it, they surely would.
As with all of these big box hardware stores, everything is very clearly laid out and the prices are clearly marked. When you find the right section (I'm usually in hardware), they have a ginormous selection. How many different picture hangers are there? Well, you'd be surprised and Lowe's stocks all of them.
Keep an eye on the endcaps and "specials" bins. I found a neat curved jaw locking wrench. A tiny thing, I couldn't resist the $1.98 price!
Security patrols the parking lot and they have free wi-fi.
