Thanks for the Orbee info--we're intrigued now, and might give one a try...

As for the Old Navy frisbees, they are just wonderful: cheap, easy on a dog's mouth, jazzy colored, great flyers, and fairly durable! When we got a box of them from the Old Navy website, I don't think there was a discount; we did it that way because our local store never had any in stock and we got tired of waiting. Now they don't seem to carry them on the website anymore, at least not that I could see. Tomorrow I'm going down to the local store to buy a whole bunch, and woe befall them if they don't have any!
