On another note: I wonder if it'd be possible to preorder kits for Flitefest, kind of like what they had as Kickstarter rewards in 2014.
That way I could order via paypal and be sure I had something to build when I get there instead of possibly going through the same hassle with my credit card company as last year.
I'd contact shop support / Jen for that. Perhaps you can buy gift cards and pay with them?
I had no problems buying stuff last year with my CC. If I recall correctly it was handled via Paypal anyway. I'm pretty sure they can find a way to handle direct PayPal on the field too
