I think Geoff got the bugs worked out of the Shop last night -- my work PC was giving me fits yesterday (and not just with non-work stuff) when I was trying to finalize everything, and I didn't go home last night from work. I just now logged in as a customer & chose Local PickUp At Event and it seemed to work... And I just fixed the default "men's" shirt price... men's & women's shirts are both $20, it's an extra $2 for long sleeve (only an option for men's shirts, sorry), and an extra $2 for sizes XXL & up (so most expensive combo is $24).
