Never knew that, I just walk out of there empty handed usually.
How much where you able to negotiate and what was it originally?
I haven't been there since I learned you can haggle with them, a friend who lives in Clifton told me about it. They write "net" next to the prices they won't deal on, everything else they will. If anyone ever gets out to the northwest part of NJ, check out Adam's pet safari, I've had great luck there, and good pricing. Dover pet shop has limited selection but possibly the cheapest prices anywhere. There's also Ely's in florham park.
