Where to find affordable awareness tee-shirts?

My family has found out about a month ago that my aunt has stage 2 ovarian cancer, she's now going through chemo treatments and I really want to raise awareness about the topic, well show that I support her, I already sport the wrist band and the key chain but I can't seem to find any affordable tee-shirts! They are all around $30 and on my budget that is wayyy too expensive.  SO I was just wondering if any of you have any good site they know of to find these shirts?

bummmmmmpppp

Relay For Life is coming up in May... you might check with any groups that are participating locally.  They sometimes sell shirts although not all will have cancer specific merchandise.  I know our group has access to shirts....

I googled ovarian cancer shirts and this is the cheapest I saw...

Make your own.  Buy cheap t-shirts.  Buy some freezer paper/butcher paper.  Make a stencil of whatever you want it to say.  Buy some fabric paint.  Paint the shirts.  Then you have a buttload of cancer awareness shirts to pass out to family members and it'll only cost you a little bit of money.

You can buy iron on transfer paper at a craft store.  Find a picture that you like, print it on your printer and just iron it on a cheap t-shirt.
