If you have donated via our Amazon wish list, we thank you! If you would like an IRS letter for your donation, please send your contact information to firstname.lastname@example.org and put "Amazon Wish List Purchaser Information" in the subject line. In the text of the email let us know what you donated so we can connected it to what we've received from Amazon. Sorry for the inconvenience. This appears to be the only way to get this done because Amazon does not give us this information. Thank you for your support and your patience!
