I think someone posted before and their unit was given a bear as a mascot but I don't think they got discount for the girls I would check you local store as sometimes they do different offers
I used to work at Build A Bear. I used to do the Guiding visits for them. You used to get a set budget from them, which is free to Guiding groups. I don't think it has changed. Let me know, how you get on.
On a similar subject I would love them to do a Brownie/Guide/Rainbow uniform for the bears surprised nothing has been set up by Guiding they would make a bomb!
thank you to all . we visited build a bear on saturday with rainbows and it was fab 19 pounds per girl with choice of 3 bears and t shirt and box games played. Fun was had by all
