The vendors have CD prices from $7 specials to an average of $13 for most new discs. A few do carry Japananese and rare items that I saw up to $25/30.
As for shirts, short sleeves run about $20 and long sleeves from $30 to $35. These prices are set by the band as they keep the money. All bands will have merchandise available.
The festival shirt will be $20, but you will have the option to actually pre-order and recieve the shirt before the festival.
I did not see any photos available for sale. There will be a section in the program with a signature page you can use if you do not want to use your cd booklets.
As for the cd sampler, I do not have that information available at the present. I would guess that 90% of the tracks on it will not be from bands on the roster.
