Hey all. I did this for Haiti last year and it worked really well. The raffles managed to raise over $200 for Haiti, and I'm hoping to double that for Japan, since YRR is out of print now. Also, my best friend in the whole world lives in Japan, so this is personal for me!
Anyway, here's how it works:
You enter the raffle here:http://www.etsy.com/shop/joannalovesyou
Each entry is $10 and there are only 4 entries per raffle, so each entry has a 25% chance to win. There are more details at Etsy.
