What is the best way using Shopify for this scenario?
User gets a unique code that allows them to access site
- No one else has the same code - but multiple codes will be sent out to different users.
User goes through products and makes a selection of 1 item
User checkouts without being charged anything
User can not log back into site.
Note: User can log back into site using unique passcode if they do not make a selection of 1 item and checkout.
This is very important.
