I believe this is still technically multi vendor, NOT multi store - I want to have my add to cart and checkout buttons show carts that have a different appearance when customers checkout at different parts of the site. So www.demostore.com/girls/store-home/user/editaddresscheckoutBT has one template, and www.demostore.com/boys/store-home/user/editaddresscheckoutBT has a different template. Actual final checkout is external, so SSL is not a factor. How can this be accomplished?
