Thank you, Carlinha, for elaborating on my overly simplistic explanation why they cost more on the secondary marketthe big markup you are getting with this particular bag is how rare it is... since now, you cannot get a chevre B unless you special order it, and this color combination (gris T with a pink) is probably one of the most coveted color combos out there. retail for a B30 in chevre is well over 10K USD, then add tax... you will probably be paying between 11-12K if you purchase a B30 chevre from the store. so you paying 17K is about 5-6K above retail.
it is very true that you will pay much less if you special order a B directly from the H store... but please keep in mind that it's not that easy to be able to special order a bag... you will have to develop a relationship with one SA, most likely buy many other H items (home goods, shoes, RTW, fine jewelry, watches, etc), probably end up totaling more than the extra markup of 5-6K on this bag... and then hope and pray you will be one of the lucky few offered to SO. depending on the size of the store, each SA will only have a few SO spots to give to their clients each season. and each season, there is a list of approved colors which changes every season... so please don't walk away thinking you can custom order any bag you desire at any time... the possibility is there of course, but within these constraints. if you plan to start delving into Hermes as a brand and can see yourself buying other items and not just a B or K, then i say be patient and wait, start going to a store and develop a relationship with an SA, and when the right time comes, SO your dream bag with them. i can tell you for a fact that i spent way more than 5-6K in the store before being offered to place my first SO. but i did not mind it at all as i love many other H items aside from their bags.
there are many many people who would consider this a grail bag and do everything they could to get it... that being said, it has to sing to YOU. to pay that much for a bag, this has to be a 10/10. you need to be DYING for chevre, DYING for Gris T and pink combo with GHW. there has to be almost nothing about this bag you have compromised on, not the leather, size, HW, color, etc. if that's not how you feel, then return it.
if you can, i would go to a store and try to get a feel for all the different leathers, ask to see their swatch book and study the leathers and colors, so you can make a more educated purchase in the future. i personally am obsessed with chevre, but it is not for everyone! maybe you want barenia, or box, or togo/clemence... the possibilities are endless
best of luck to you!!!
Great point about the same SO combos not always being available; I never thought about that beyond the options that are no longer available like tri-colors, etc.
