Agree with this. What drove me mad a little were the inconsistencies as well across regions and boutiques/department stores. I purchased a few times in the last three years or so from the boutique in London, as well as Bloomingdales in the US. When I visited in the last few months, the London boutique and Bloomingdales found my profiles but I don't think they were the same profile (perhaps different systems or something).
More recently, I tried to order a bag over the phone from a
Nordstrom Chanel and the SA couldn't find my profile and told me I had to purchase something from a US boutique before she could help me. I went to the Chanel boutique near me but they found my profile immediately even though I had never purchased anything from a Chanel boutique in the US, which completely contradicted with what the other SA told me
Sometimes I wonder if the difficulty in purchasing a bag adds to its appeal of elusiveness which makes us want it more
