I have been doing that - leaving name on waitlist for certain bags all over 3 boutiques. It never works
I think even though it is not a quota bag per se, but you need a relationship with an SA that would give you better bargaining power because you need someone on the inside to help you look out and score the bag and keep it aside for you. They are not going to do it for anyone whom they don't have relationship with so in the end, it is you still need to spend and spend and then hope your SA manages to score for you.
On this topic actually, I also wanted to check, if it is recommended you give the SA exact specs or just tell SA any specs would do, would that increase your chances? (for people whom are trying to build profile)
Because like I did tell my SA any colour to increase my chances or to get one faster, but I also note that people say that Hermes system is very fair. For eg, if they have already sold you a mini evelyne this year, it is very unlikely you would be offered the mini evelyne again in the same year, as you have already gotten it, they are very fair and they would give to other customers who have not yet purchased it rather than you if you have purchased it before. So I was just wondering if it is better to just take any colour or to inform exact specs, would it be much harder to get? Thanks.
