Short answer is unlimited sites.
The only limit is the five free basic sites with the CC membership. There are partners on BC that have many, many sites on the platform.
So just to be clear, if I pay 16 dollars per month, and obtain the webcommerce package, then I can host unlimited sites through that package?
Let's take a step back. Each site plan is on a per site basis.
You have five free basic sites with creative cloud membership. If you upgrade a site to the webCommerce package you would pay the standard rate of $38.88 per month (US Pricing) for one website. Want a second website on the webCommerce package? Then you would pay another $S38.88 for that site and so on. If you upgrade a Creative Cloud site to a paid site that site will then again become available for another free site.
Hope that makes more sense.
Ok. That's what I was looking for. Thanks so much.
