Ehh, you're good and so is the product. It sits on a UPS truck in the summer sun for hours before hitting your door. Bounces around on the truck or airplane, not to mention the package probably gets tossed around like a frisbee.
A few labs have done studies on this ('ll see if I can dig those up), but end of the day they are fine left out if room temp in a dark cabinet. Light is the enemy and so is sustained head with time. The shipping aspect won't matter at all. We're talking weeks before accumulated "damage".
