According to CS:
Every subscription will always begin with a Welcome Box. This box is an introduction to our service and will contain some of our universal favorites and best sellers.
This seems weird to me, because according to site FAQ and an article CS sent me:
• Brace your mailbox! We'll send you the current month's Birchbox within 10 days. It will always include five personalized beauty samples from across categories (hair, makeup, skincare, bod—you get the idea).
What is a Welcome Box?
A "welcome box" is a Birchbox filled with our best sellers that work for everyone. A welcome box is the first box sent for all gift subscriptions.
Has this happened to anyone else?
