If you're willing to splash out $99.95 for Super Mario Galaxy 2 at Gametraders, they'll throw in a Super Mario Galaxy 2 t-shirt for free.
And if you're cool to stump up the same price for StarCraft II, they'll throw in - yes! - a StarCraft II t-shirt for free.
Both offers are listed in the June catalogue, but are only available while stocks last.
Elsewhere in the catalogue, the clothing theme continues with a heavily discounted Tekken 6 Limited Edition coming with a Tekken hoodie for just $79.95.
And Bayonetta on PS3 for $29.95 seems like a good deal to me.
