There isn't a lot here yet because the really big deal is going to be when I have my store back online, but I do have a few items available (2018-04-08 Update: or... maybe not available; Zazzle links seem to be down) via 3rd parties:
"Transition in Progress" shirt available from Spreadshirt - multiple colors and options; will customize the design on request
"I Am Not Under God" mug available from Zazzle
"You Can Have My Stupid" bumper-sticker at Zazzle
"Annoy a Republican" bumper-sticker at Zazzle
I also have "ask why" and "use logic and reason" for the 2nd line ready to upload.
I haven't yet turned these into finished products, but will do so at the least suggestion:
