Can I create an online store with tribefii?

Yes, you can.

tribefii comes with a Product Plugin (plugins are building blocks that provide certain types of functionality) that allows you to set up a product catalogue that can be included in your Microsite.

You can set up multiple product pages or Microsites for different products - this allows you to create different branding and positioning for your products, from a single account.

You can configure different payment methods for each of your products if you need to.
