No offence or anything, but it seems like you only want one shirt, in which case why not just buy one and donate the rest of the money you'd have spent on the others directly to charity? It's only the profits of the shirts that will be donated so the charities would get more money if you paid the $24 or whatever it is yourself, opposed to some undisclosed cut of whatever the price is - manufacturing, storage, personnel fees etc... Still, props for doing it, I know I certainly haven't got the money for it, especially being unemployed in the UK with the massive shipping fees!
