What would you change it to? UPC codes? One of my games has a UPC code of 000888834625. Try reading that quickly on a product tag. Short hashes like jKghH3? How do you convey that it's case sensitive? Otherwise you have to make the code longer and more complex because they have a LOT of products
BestBuy is a technology retailer. Use of technology looks good for them. They have an extensive marketing department because that's how they get normal people to shop there. It's been said this is a marketer's technology, not a user's technology. Who cares if people whip out their smart phones? Their product tags are all computer generated anyhow, it doesn't cost them anything if people use it. But what if this QR code just happens to get someone to check out the reviews and buy this product? Or what if it ever so slightly changes the perception of some parents that BestBuy knows what they're talking about, so they go there to buy their kid's electronic gizmos.
Keep adding sensible folders as is needed, words that customers can remember and numbers that are easy to type in. Hey the QR can still point to this, but give me something I can type in, or even remember and look at later.
By only using QR you are telling the customer that they are too stupid to type in a URL, to lazy to remember one, yet tech savvy enough to know what the barcode actually is.
