I ordered a Wyyeast smack pak that was shipped on 13 October. Got it today, 16 Oct. The pack was sealed together with a coldpak in another clear plastic bag. The coldpack was not frozen but it was "cool". The smack pak had not swelled. I placed it immediately in the refrigerator. Do you think it's ok? Would the package swell if it got too hot in transit? Thanks for any information.
