OP, I wish that I could help you or offer some advice that someone else here has not already said. My personal experience started with buying scarves for years until the SM actually
insisted that I consider a bag. After I decided what I wanted (I gave a short list of what I liked), I waited a total of three days for the store to get it in stock. I never played a game, I never kept track of what I spent, I bought what I loved and then it was just a natural progression for me at the right time. Of course, that is just my experience, and yours is different. Since I can't help you in that regard, I can at least bring up a few things you may want to consider in your search for your B.
Even now when I make a request, it's for a range of colors (say, for example, a true red with blue undertones, or a list of similar colors: braise, rouge VIF, vermillion etc); it's nice to know exactly what you want but as pretty as gold is, if you do a little research here or on the H website you may find that you can at least give your SA a few options. The only specific color I ever requested was black, and that was after quite a few bags (for a long time I felt no need for any black bag). I may have missed it, but I don't think you mentioned anything about what kind of leather you wanted, and that is something you ought to consider as well, as the various types of leather have pros and cons, and if you truly only want one bag (it is a REALLLY slippery slope! Everyone wants 'just one'!
) it's a good idea to know about them, even if it's just to say you're ok with leathers x, y and z.
Another perspective I can give you is on the other side of the resale route - I have had a number bags I haven't kept, for one reason or another - for me, I find I need to live with something for a while to see if it is a "keeper". Some resellers are just flipping brand new at a premium, but others have bags that were genuinely loved but are being let go of for some reason. I have found that I prefer certain leathers, certain sizes didn't ultimately work out (my kids grew older and I could say goodbye to the larger sizes
), my wardrobe changes (currently DH keeps buying me scarves with green, is this a hint???). I thought maybe if you knew why there are some reasonable resellers with authentic bags, it might make you feel just a bit better about that option.
I know this doesn't really help in your quest, I just thought to offer you some related food for thought.
