I ordered 2 packages to qualify for free expedited shipping, and ordered on Monday morning as recommended. The capsules were shipped in a styrofoam box with ice packs inside it, during a period of 35-45 F weather in my area. Nevertheless, the package arrived warm, the ice packs were totally melted, and the boxes inside appeared to be room temperature. I quickly put them in the frig and hope that they'll be effective. But I'm quite disappointed that even with all these efforts they were not kept cold all through shipping.
