Where to buy t-shirts of metal bands

Hi folks,
do you know some shop in munich where I can buy tshirt of metal bands?

thankssss

best bet is at concerts of those metal bands. How else can you prove you were there, that you heard of them first?

Rock / metal band t-shirts might be of some use.

Keydecks response is about as good as you're gonna get.

However, PLEASE don't be the typical german and wear the band's t-shirt to their own concert...it's just wrong.
