I'd ask for more pictures. First quality these will be $730-ish and, in all seriousness, may not be available in the right size for months, even years, as first quality. And we all know first quality is a curious tag, at least with respect to how Alden defines it.
I've never bought a pair of Alden irregulars, but there are situations where one might consider it. Perhaps this is it. If the guy paid 399, and you pay 579, who cares if he makes some money? If you wait to get this shoe in this size on TSMs irregulars listing, you might wait a handful of years - no joke. Many times TSMs irregular listing has zero whiskey models, at least in many sizes.
Lots of guys on this thread talk of how exotics are hard to get, etc., etc. I suppose that is true, and certainly "hard to get" is relative, but, in my experience, exotics are not exceptionally hard to get if you diligently search and pounce once the opportunity presents itself. How many on here kick themselves for not pouncing when they should have?
As but one example, a few years ago I bought a ravello shell captoe blucher on ebay (very lightly used). I saw it; I pounced. It is one of my favorite Aldens. At the time no one carried that model, and to the best of my knowledge no has carried that model since. Side Note: today I am wearing his brother, the cigar shell captoe blucher from Alden SF.
The whiskey LWB is a grail shoe for many. It's not for me, but I do own it. It is very unique.
