I bought this succulent last night after visiting Home Depot. I had seen this particular succulent in the Cacti & Succulent display all summer long and never bought it. But last night it looked so sad sitting there among the carnage of dead or dying C&S, that I just had to buy it. I have no idea what it is other than it is some kind of Crassula if I am not mistaken. I really like the faint coloring at the edge of the leaves and the "spotted" leaves make it pretty interesting too.
EDIT:
This succulent turns out to be an Adromischus which is native to South Africa.
