From now until June 18, the official MGM Stargate Store is offering free shipping on any orders over $30 US. They’ve reported to Solutions that their most popular item right now is the incredible disappearing mug, in which the team “disappears” through the Stargate event horizon whenever hot liquid is poured in, only to return when things cool off. A nice way to keep SG-1 alive and going on missions… in your kitchen.
