Hide Products and Secret link are both available in Premium plan ($50/month).
On the one hand, Secret link is more private than Hide products as the whole page is locked.
On the other hand, let's take an example to see how you can practically apply the options:
Suppose that a collection page includes both wholesale products and retail products.
- Customers with b2b tag will just see wholesale products on this page
- Meanwhile, customers with b2c tag will just see retail products
- Store owner will send the secret link of the wholesale product page to wholesalers only. Those customers will see the whole content of the page while other customers, such as retailing customers, can see nothing with the normal link.
Hope the information helps you.
