August 12, 2012 - Toys'R'Us has a coupon you can print and use in-store, good for $5 off any purchase amount. The usual mountain of exclusions apply - no baby formula, gift cards, and so on.
The coupon is good from August 12 to the 16th, so hopefully your local store has something in stock. If nothing else, maybe grab a small item for the holiday toy drives that are coming soon.
Forum reader Jeff posted the link to the Facebook version, and the coupon is also showing up in emails from Toys'R'Us.
