It's really just a warehouse where I could pick up my merchandise.

> Was there no knowledgeable staff?

No, and That's certainly not the trend these days. I did ask an associate if I could just take the assembled grill to the cash register (and I could).

Your comment made me think about the real purpose of brick-and-mortar stores in the age of Amazon. In this case, the big-box retailer served as merely a display room for me to physically inspect the product and a place for me to take immediate delivery of the product. All the information gathering can be done by me, using the information on the box, or through my mobile device (with the QR code being the relevant portion of this discussion).

> No product flyers/labels?

If used properly, a QR code (or whatever vector allows me to find information online) can provide much more information than labels or flyers.
