Hmm. Ok. That looks like a different kind of company in that it is bringing together the companies and the non profits as opposed to a non-profit getting a donation from a company to use in an auction. Have you tried to directly reach out to American Girl?
The person before me shared she received an American Girl donation from Good360. So I went on to learn more about the company and see if I could register my school and that was one of the rules and regulations? good360.org/marketplace/register/501c3/terms/
I'm trying to register and one of the rules is : DONATIONS CANNOT BE USED IN CONJUNCTION WITH ANY FUNDRAISING ACTIVITIES, SILENT AUCTIONS, OR AS PRIZES...
