Sami B2B Lock,Password Protect

One of the best apps i've used with my Shopify store. I'm using it to gate certain product pages so they are only accessible to e-mail subscribers. Very easy to use, and any help you need with be easily accessible via the live chat. The team are extremely friendly and are more than happy to help you with any issues, such as removing any branding and changing the default image. They also help out with any placement requests, all done within a few hours of messaging.
