Hello, I´ve been loocking for and extension for this:
If you are a guest, yo only can access a limited product pages (per day for example )
But if you have paid a fee, you have unlimited access.
The first thing is for give to simple costumers the possibility to see some products for personnal and non commercial use; the second one is for companies who use the information for commercial uses, and have paid for have unlimited access to the catalog
As you can see, the site is not an store, is a catalog.
Thanks in advance
