Basically I am looking for a Shopping Mall system in PHP. User included

• Üye / Kullanıcı
• Yönetici
• Satıcı
• Bağlı şirket

Birden dükkan destekleyen bir çok e-ticaret bulmak, ama her satıcı kendi giriş ve yönetimi yok.

And in the front I would like to share the cart. and can buy from different shop. If multiple subdomain supported that would be more better. Web 2.0 design would be much more preferable.

Any suggestion? I google some of it, hopefully can get more references. Buy / Open source also please advice. I don't think this kind of system got open source :p
