Check a few others as well !! Doesn`t have to be the exact same one you have but it will give you a better idea of what people are actually paying !! I think they are a pretty good find !!
I looked at the other one and it had a $500. to $1000. estimate !! So tell your wife to put her leash away and open the doggie door:) !! Better yet give you a treat for this find !! 🙂
