1) Any of the Alden branded retailers. Most of the smaller stores that stock Alden also have a few pairs as well (I've gotten some from Leffot before)

3) This appears to be an Alden DC exclusive
I was just goofing around, since these 3 questions seem to be reoccurring so regularly.
I thought if you can't beat em, join em.
