Your Shopper profile is the same as your Stager profile. What makes you a Stager is posting short videos, called Styles, showcasing the products you buy.
Whenever you get a new item or just want to share your style, record a short video and upload it like you would in similar social media platforms.
As your follower number increases, you will rise in the Stager Ranks, which will allow you to participate in more cashback promotions.
