Bonfire, newly improved and updated and formerly known as Bonfire Funds, is an awesome site we have used for 3 t-shirt fundraisers, to raise funds for both our adoption and for our childrens ministry in Uganda.
If you want to do a t-shirt fundraiser, and you use our link, you get an extra $1 per shirt, and we do too! (up to $100!) We love this site, plan to do many more fundraisers in the future, and highly recommend it : )
