There is no way we can get it cheaper. Unless you have a good good friend working in LV and she doesn't mind to share their quota with you. Or you can ask someone you know very well to buy for u in Europe. Be careful if someone you don't know tell u that she can buy for you at a lower price, it maybe a "A" good.
$20000 is not much, only 2-3 bags a year. Think carefully, why would they(LV staff) buy for you if you don't know them. I am sure their family or friends are hoping to buy at a discounted price also.
I always go to Paris before but I would not buy LV for someone who I don't know. Because I rather sell the LV bags to "water goods man". I could sell those LV bags to them and make $$.
Don't believe you can get it cheaper from someone.
10 years ago, there was a shop selling LV at a discounted price in Tsuen Wan. I went in and I heard the sales lady saying that their bags(actually A goods) are water goods and bought by airline crew.
They really made good $$ cos I saw a lot of women paying $$. The shop closed after a short period of time.
