So the way it works, you sign up for the Sony credit card and use the instant approval to purchase the PlayStation3 for $499.99. But your first purchase of $299 or more earns a $150 credit back to the card – reducing the PS3 to $349.99. Sure, you could buy something else to earn the same credit – but what’s more appropriate for a new Sony card? Get a PS3 for gaming and Blu-ray for less. And don’t forget the five free Blu-ray Disc offer is still running, so you’d get five free movies as well. The deal is good through August 31st.
