Alright! I've sent the required payments to the printer and have sent a request for payment to everyone who signed up. I've closed the form, so if anyone is still interested and you have not signed up yet, please send me a PM.
There will be extra posters at the event, but with some 150+ attendees, if you are interested in a poster your best bet is to commit now. Also, I will not order an extra run of prints unless this first batch sells out.
Final price is $25.
Thanks everyone!
