The saleslady at Learning Express told me that if there is any wear whatsoever and you are not happy about it, just bring it back in and they will replace it, no questions asked. My friend's dog chewed up some of their Thomas track and she called Learning Curve. They said they would replace it free of charge!
The only Brio I've ever seen at our Tuesday Morning is a small set of trees. I keep checking but haven't had any luck with trains. I should put Neve on the case - she's the one who always find great things there!!
