Maybe you can host a few T-shirt design compitions. Winner gets his t-shirt for free. Others who get a design selected get a free X-H2O.com sticker. A sticker is just like a "hey thanks for playing prise" since the goal is to develope revenue for the site that is more fun than just mailing out a check.
You can use these shirts as give aways, but you could also sell them on a daily basis to anyone who is interested.
There are several print-on-demand companies out there for T-shirts. What they do is... Say they want $10 for your shirt. You pick a price over $10 and set up your little online store. They handle everything... so you sell your shirt for $15, they wanted $10, so they send you $5. Might be a good way to scrounge some donations.
This same idea works for lots of things, like stickers and post cards. You can even sell X-H2O.com panties for the ladies. Now guys, what would be cooler than your lady dropping her britches to see a picture of a super jet on her panties under a caption that says "Get wet and ride hard"? And you can have it for only $14.99.
Here's on site that does print on demand.

I haven't checked it out but I know there are many sites that will print your shirt for the price you set and keep part of the $$. No cost to you except the time to set it all up, because there's no cost until they buy, and they buy for more than the cost, you just get the check.... I think...
