If you're tall with 36-37+ shirt sleeves and like Isaia shirts, ebay seller sarafsaraf seems to have cornered the market in a recent batch of them at reasonable prices (like $139 each). If only they were 35 or 35.5s, I would have snagged a bunch.
Not spam, and I'm not affiliated with the seller, just passing it along.
edit: Hmmm, just realized they're shipping from Italy for $30. Probably not worth it unless you are getting multiples and they will combine shipping. Also, remember you'll probably get hit with a customs duty of some sort. Suddenly doesn't sound like quite the deal, but YMMV.
