This time I got $11.60 because I bumped up the length to that 32" you mentioned, weight I chose was 15 oz since posters don't weigh much and tubes don't weigh much, if it's over a pound it cannot ship first-class. Because the tube you're sending is 32", your max diameter of the tube cannot be more than 5" (keep in mind that they generally round up, so 31.5" is 32"), if it was larger than 5" in diameter then they couldn't send it International First Class, but 5" is pretty big for a poster tube, mine are 3" and hold a dozen canvas posters each.
