Query: Bars arrived degraded by heat

These bars were shipped from Phoenix, AZ, in July. Need I say more? While they are edible, the chocolate coating on the outside had turned a very light brown and the consistency was changed. They taste OK, just not as good as they do when they are not exposed to extremely high levels of summer heat. I feel it was a bad decision to ship any perishable food items from Phoenix, AZ, in the summer time. I will not order these from Amazon again during the summer but will look for a place along the west coast or in the mountains where the bars will have a better chance to arrive tasting their best. These bars are normally really good bars, some of the best protein bars around, in my opinion.
