girl guide uniform : eBay Guides

Its good to see so many young people still interested in joining uniformed clubs such as Rainbows Brownies and Guides. But why does the uniform have to be so expensive? My daughter was in the Brownies for 3 years and she had most of the uniform thanks to sellers on ebay. Now at 10 years she has joined the Guides I looked in the local uniform shop but went back to ebay.
