How many stores can I have with my subscription?
You can have only one store per subscription. You can have as many domains pointed to your store as you want and as many funnel pages directed to your store as well. If you have different niche marketed products and can incorporate these in to one store you can create multiple pages within your Studio Builder to attach different domains to and with links to various places within your store for that featured item or items in that funnel page. If you do not want your niche products to be in the same store you will need to purchase multiple stores to keep them separate.
