Well, it depends on what business Best Buy is in. If they're just a vehicle of getting merchandise to customers, you're right; it's not their probem. However, they're going to lose to Amazon in a heartbeat since they'll never be able to win with pricing. On the other hand, if Best Buy offers you personalized assistance in making the right buying decision, they've created a value proposition that Amazon can't match. This is what they claim to do in their brick and mortar stores.

In the case of the article, they're clearly going after the convenience market, but it's my opinion that attaching their branding to it then not following their brand-standard policies is a little disingenuous.
