SO every boutique is entirely different. They order based on (usually) what they think their clients want. From here on out, and a new rule (not sure if all boutiques), Chanel will disallow any reserves for leather goods priced under $8k. Just a side note.
This particular boutique ordered for jumbos: White Light Beige Light Grey Green (the darker one) Pink and some other color I disregarded (probably yellow LOL). Other boutiques will have ordered a different combo of colors off this menu. All of these might not have been available to order in the US, and also, once ordered (months ago) Chanel DOES cancel colors. So boutiques really don't know what they are getting until NOW, when they are told what their allocations are.
For instance, 21k, O cases (large size) were available on the "order" menu in all of those beautiful iridescent colors!! My boutique ordered them for me. When it came to communicating what they were GETTING (allocations), that entire line was cancelled 100%. Which sucked, royally. I managed to get all the minis, but had not ordered them thinking I would get the O cases.
Does this help make some sense of how it works?
