Hello again for a final update. All the auctions are now over and we've raised over $1,300! I'm honestly blown away by how great the response has been to this! I'm going to be adding in a personal contribution so that the final donation can be an even $1,500. I have to wait for the funds to clear from eBay/PayPal, but I'll post something on Twitter once I make the donation.
THANK YOU AGAIN TO EVERYONE WHO BID, RETWEETED, OR SAID SOMETHING NICE AND ENCOURAGIND. I hope I have an opportunity to do something like this again in the future.
