CAG gives some shopping advice for this rather lucrative deal: "In case, you are afraid of this being out of stock when you get there, I just tried this and it works, Buy it here, then choose in-store pickup and your credit card will be refunded about ~$41. A CC representative just called me about this so it is confirmed."
Good luck, shoppers.
Update: Unfortunately, it looks like the deal is dead. Guess it was a glitch that was corrected -- maybe we publicized this deal too much?
