Thank you for your question. I don't have any physical products available for purchase online, but I do have some that I take to trade shows. If you would like to email me at firstname.lastname@example.org, I'd be happy to try to work something out for you.
As of this point, all I have for WWI is the World War I: Research and Notebooking Unit. A quiz pack is on my future to do list, but I don't have an estimated completion date yet.
