how much are tour shirts?

TBH, Allan's post made me wonder if everyone else was being really conservative too. Most of the US tours we've done we've been the cheapest on the bill @$20 for a shirt.
 
On Warped, all shirts were at least $20, with the larger bands like ADTR, ABR, etc. charging $30.

At the DTB, Dimmu Borgir, and Enter Shikari shows I've seen in Dublin, shirts were €20, CD's at €12. Saw ADTR in London 2 weeks ago, shirts were £20, FWIW.
 
In Finland it totally depends who the band is. The most outrageous I've seen was 45€ (~$60) for a t-shirt, can't remember what the band was, but I think it was Korn. Anyway they sold them way more than they should've for that extortion price. But normally they vary between 15-30, usually around 20 for a t-shirt and cd's are 10-20, usually 15. Hoodies also vary a lot, cheapest I've seen was 20, most expensive was like 80, but it had some embroidery on it tho.
