I was trying to recall this morning whether B&N carries the magazine (and thinking I should stop by and check sometime soon). It is available in electronic version for their Nook & Nook apps, but I don't recall if I've seen the physical version in the store. And THR does have what looks like a pretty easy to use on-line store, for any interested:

Can't wait!
