Here’s a puzzle for you. B&N just cut the price of the Nook e-reader by $60. Over the Father’s Day weekend, the Nook was $259 with a “free” $50 gift card. One PC World reader who got this deal called B&N to ask if he could have a refund of the price difference and was told he could only have $10 because he got a gift card. Now he wants to know if he’s been shafted.
