I've been looking to get my first NIB pin and while a couple distributors have been helpful and taken the time to answer my questions even if they don't immediately have what I want, I feel like most distributors I've talked to give very short responses and won't even respond to follow up questions if they don't think they'll get an immediate sale. Is this normal? The impression I'm getting from a lot of these guys is that I should consider myself lucky to do business with them.
