You got a very good deal! I didn't see anymore of the doubles for what you paid. I have a Pet Gear and mine really like it. It doubles as yet another dog bed when I don't have it in the car.
There are some other good deals on that site -- thanks for passing it along!
I had never seen a doggy high chair that clips to the table!
I probably wouldn't get it since we have worked so hard at not begging at the table but I thought it was cute.
