you need to create three website under same admin of magento.
you can assign product website wise and also you can manage price per website also
Can each of the sites share a theme/template and still have separate configurations for each site? I'm trying to figure out if I need to purchase one theme or one for each domain name we run.
@Sunil Patel I know what I need to do on the admin side.
But I get confused on what I need to do in my files. Some places say I need to update my index.php, some say I need to edit my .htaccess and index.php.
I am also unclear on the domains themselves. Will they all point to the same IP address?
If that's the case, what do I do about SSLs? Can each domain have it's own SSL?
Let's example your site localation is /var/www/html
inside you need to create one folder for website 2 e.g site1 inside that you need to copy index.php and .htaccess file.
for site 1 domain you need to link to /var/www/html/site1
same for site 2.
for ssl i think it is different per domain, you need to ask to hosting provider.
