I like the QR codes at Best Buy; I use them all the time when I'm just starting to research electronics and I make a visit to one of their stores. It's convenient, I can store it on my iphone for later, and I can read user reviews, etc.
That being said, I'm not sure if they help or hurt sales because when I do scan a QR code, I typically end up doing comparison shopping and typically Best Buy's prices don't compete well with online retailers.
I'm on the wrong side of the planet to check, but I'm bet reasonable money that Best Buy are running privacy-dubious redirection/browser-fingerprinting/analytics on the urls those QR code send you too.
Or if they're not, does anyone have a contact in marketing at Best Buy?
