Sony Gift Cards 20% Discount

I just got an email from Sony offering a $20 gift card for each $100 gift card you order. From what I read about the offer, you can buy a $1500 gift card and get a $300 gift card free. They'll email the gift card to you, so it's immediately available. There is no expiration date.

Personally, I don't need anything from Sony right now but this might be a good offer if someone is getting ready to buy something.
