Flash storefronts
Give each group buy host, influencer or physical store their own separate storefront — its own URL, its own product selection, its own sales figures.

How this differs from affiliates
Affiliates is "one shop; bring people in and earn commission." A flash storefront is "open your own shop" — the host picks which products to carry, orders them how they like, and has their own store name and cover image.
This suits social group buying, parenting-community hosts, and physical stores running their own operation.
Question: Do flash storefront orders get mixed together?
No. Every order is tagged with the storefront it came from, and sales and payouts are calculated separately.
