Check with the Den Leader and the Pack Cubmaster, they may have a lead on some used shirts also. When my son joined, another scout had quit and his parents gave the shirt to the den leader and told her to pass it on. We were the lucky recipients

I noticed you are in Wisconsin, you also might want to check
www.madisonstuffexchange.com or look on ebay. Sometimes good deals can be found there. Some packs also have exchange programs....something else to think about. Good luck!!
