Do I Have To Upgrade To Multivendor For Making A Second Store?

If you are using cs-cart ULTIMATE (not MultiVendor) then:

1) SSL's are by domain so if you have example.com and example.com/store2 then you only need 1 SSL However, if your customers will access your storefront as store2.example.com then you would either need a wildcard SSL certificate for *.example.com or you would need separate SSL's for the main domain and the sub-domain.

2) Themes are independent so yes, you can use different themes in different storefronts

If you use Responsive them then there is no need for separate stores to present to different devices unless you absolutely have to have a mobile-only site.

Thanks EZ,

1.Can I add the 2nd (already purchased) store to the admin of the ultimate I am now working on designing but not yet live?

2. If yes, where can I find the instructions to add the store?

3. I want to add as example.com/store2

Thanks again

1) yes

2) Manage storefront selector in upper left of admin header. See the knowledge base for detailed instructions.

3) Again, see the knowledge base on different options. I would suggest you use a sub-domain versus a sub-directory.
