Got my shirt-and-bonus-candy today. I was surprised none of it melted, given how hot it's been, but the shirt was wrapped in its own protective tissue paper, so it probably wouldn't have been an issue. Some of the candy looks safe, but some of it I can only classify as sketchy loose hobo candy and will give a wide berth.
The shirt is nice and soft, though, and the design will no doubt confuse many an onlooker for years to come.
