It's quite impossible to know who's scamming whom (wouldn't that brick weight a lot more than 7 pounds? Wouldn't it obviously slide around in the box?) but given Best Buy's defensive response to the latest "brick in a box" claim, it's hard to trust it. From The Consumerist:
When I got home I opened the box and found a paving stone packed with bubble wrap, instead of the Macbook Pro. I returned to the store and the manager, "Keith", was not too willing to help me out. ... So right now, I paid $2164.89 for a very nice red brick.So you claim, shopper! Best Buy looks guilty, however, because of that manager's claim that Apple sealed the box at the factory. This is a terrible excuse, because shrink-wrap machines are cheap and found in abundance in the inventory rooms of consumer electronics stores. Also--haha--Apple doesn't shrink-wrap laptop boxes. Folks, the rule for Best Buy is that you open it up before you leave. This is because Best Buy doesn't have secure inventory management and won't take responsibility if its staffers screw you.
