I gave up on Halloween stores for purchasing my wig. I went to the California Merchandise Company in Santa Ana and found a beautiful wig labeled "50% made in USA, 50% made in Japan".
I also went to BigLots recently to finish putting together an earthquake kit. One of the items on my list was rope. There was no rope there not made in China - thick, thin, nylon, cotton, bungee cord - all made in China. The search goes on.
