The $15. PlanetRX and $10. Bigstar discounts are shown on the food.com front page (Bigstar not CDNOW, as I said/thought before). You should get a planetrx code emailed to you, and it appears a bigstar code as well. Not sure if they will be coupon codes or even better giftcertificate codes (which might then be used with other coupon codes).

happy shopping.

So it seems the food.com payout is about 5 mypoints per dollar, not bad.
