U can go often but stop stating about your spending so obliviously. The US / Europe works a bit differently from Asia. Good point that if u want the exact size and classic colors, spend at your local stores constantly and u’ll get it after some wait.
Your biggest mistake was being so oblivious about pre-spend, of course the SA want to secure customers with high spending power, but telling them you're willing to drop all the money in exchange for a bag offer make you look desperate, and they're actually trained by corporate to NOT offer the b/k/c to clients like that. I have friends who've spent over $500k USD on Hermes for several years and never gotten offer a Kelly Pochette or mini Kelly, it wasn't until a few months ago that her her SA felt bad and finally offer her to make a SO, so she finally able to get the perfect mini Kelly. My point is, it never work when you just offer high dollar purchase, whatever the SA willing to offer and can sell solely dependent on their SM. If the SM doesn't approve it they won't be able to give you an offer even if you've dropped a lot of money on pointless items.
