I bought some zoas from a seller on this site and they arrived today. They were shipped priority and it took them 3 days to get here (WY to CA). I opened the bags and they smelled RANCID. They haven't opened yet and I'm wondering if they ever will. I know I have to give them time, but that smell really worries me. How long should I give them? I've never ordered zoas in the mail so I'm not sure how this goes. Any help would be greatly appreciated. Thanks!
