Bait & Switch BS at Home Depot! (Caution! I'm still worked-up here...)

I've purchased several items from the local Home Depot where I go into the store and find what I want. Then look the item up online with my phone. The online price is often cheaper than what the shelf price is. So, I order online for local pick up. I go to the counter to pick it up and a clerk often goes and gets the one I just looked at on the shelf to fill my order.
