I had gotten a big bottle from JCrows. When that bottle's gone, I'm not sure if I'll continue to buy from there since I'm an odd lady who hates to shop, and JCrows isn't selling the 5% in the larger quantity anymore. I didn't stock up on multiple bottles like some people because I don't have space for storage. The one big bottle will last me quite a while, even with painting. I may start painting with just povidone (Betadine), since it's OK for external use and is easily available from any local pharmacy or grocery.
