Making a shopify shop with per-user discounts

With the launch of Pile-Up Poker we knew that we wanted to sell a pack of cards. Systemically thinking, this meant a few requirements for what it would mean to buy a physical item from us: We want admins to handle inventory We want to work with third party fulfillment tools We want people who sign up during the launch period to get the cards for free We want folks who had already signed up, to get it for a reasonable price Folks who don’t want a Puzzmo subscription could have a route to getting the cards There was a strong recommendation from the business side to use Shopify, and we didn’t have any argument against it on the technical side!
