I think there must be a problem with your postage calculator. I wanted to order 9 3×3 stickers. Postage came up at $72. Surely this must be a mistake? I sent a 2kg plum pudding to France last week and it cost $93. And I know we are in Australia, but we are on the same planet. It’s not like you to have to have someone deliver the stickers to NASA and have them sent on a rocket to the space station.
