Hello, I'd pledged for one pin, but wanted another when it came to surveys, so I added one in addons, and my $10 shipping turned into $20 shipping. Is that right? Or is there a problem with how my account is adding up shipping? I've changed it back to one pin for now, so I can make up my mind about that, haha. No worries if that is what it's supposed to be for two, I just thought I'd double-check. Thanks :)
