Hi guys. Feel like I'm being really stupid here but I cannot figure out how to add different sizes for different variations of my poster. I'll attach the price section I'm viewing when I'm trying to list my first poster but I actually just cannot figure out for the life of me how to do it lol. PLZ HELP! Also how much more do people roughly charge for US orders (I'm from UK) and 'anywhere else'. Should anywhere else be the most expensive for me or just USA?
