I ordered something from Haberdash that was OOS. But the service was great: multiple, professional emails through the order process. They even tracked the package down after I said shipping was maybe taking a little long (hi I'm Canada). They replied promptly by phone, text and email (it was one last day away).
Plus, the prices can get quite low: I grabbed an SNS Reference jacket for $200, down from $500+, along with a few other things.
