I'm going to take the BB advertisement from the paper up there tomorrow, and ask where my pre-ordered Bolt is, and when they tell me they don't have it yet I'm going to try to get a free case or screen protector out of it. I'm not a charity, and I'm not in the habit of giving out temporary loans of indefinite duration to major corporations so they can collect on my interest.
Now, while an advertisement is not an offer to contract that becomes enforceable upon acceptance (unless it gives a specific date, quantity term, and who can accept the offer, eg. "First come, first served, on 2/20, while supplies last"), the Best Buy ad is at least deceptive and misleading because it implies they will be available for sale tomorrow (says "new," has a price term, but no date, no language about a pre-order, does not say "coming soon"), and I'll claim that I drove all the way over there in reliance on that advertisement and require some sort of restitution for their failure to produce. We'll see what happens.
