Question about upcoming SS

Hi all, it’s my first time getting an hermes sample sale invite & would love some help with a few questions:

1. If I got an invite this year will I be invited back every year? Or do I have to be re-chosen every time?

2. Does the sale restock during the week? Unfortunately I missed the email invite & was only able to book the last time slot available on the last day, wondering if there will still be product left.

3. Any recommendations that previous attendees have about where to spend most of your time / what the best deals are etc.

Would love to hear people’s experiences! Thanks in advance!
