I've been collecting *H* scarves for many years (almost 20?). Some came from various *H* boutiques, and the others came either from consignment or duty free shops. I also have two Constance belts, both of which came from consignment shops and both brand new. Neither one had ever been worn.
I only started buying the bags recently, within the past couple of years, and they all came from reputable resellers (no ebay -- thought it was too risky). I decided to deal only with the resellers after hearing conflicting stories about the waiting lists and people ordering a bag with certain specifications, then after waiting for months, being offered something entirely different, having to invest $$$$$ in buying other items in order to cultivate *relationships* with SAs, etc. Of course, after joining this forum, I've learned that not EVERYONE goes through the above to acquire their *H* bags. But I have no regrets. I would say that my experiences with the resellers have all been positive. In each case, I got exactly the bag I wanted at a decent price (on par with what I would have paid at the boutique, give or take a few) and the service was great.
I don't care that I missed the whole buying at the *H* boutique experience and being the first to unwrap my bag. That wasn't important to me. All the bags I got in the end, except for one, which was very lightly used, were brand new (one even still had the plastic on the hardware). Getting the exact bags I wanted without having to wait months or years was my sole priority and I couldn't be happier.
