Also @n1hal,
The reason Mene asks your address is that when you order they need to deliver. Hence details are taken upfront. Doesn't look like a site which should worry you. They also have a presence on Steemit. If you have any doubt, they can clarify. Hope that helps.
Ya surely can I just have a link to their steemit account so that I can go through some of their posts to understand more.
