Twitcher, I use a small box since I don't have to buy it like I would a bubble mailer. It goes as a "small package, thick evelope" first class mail. If I don't use the $0.19 Paypal delivery confimation, I can ship for around $1.75.
C-mail me your address and I can mail some Olympicum.
Oh boy, something else to grow from seed. Now I'll have to try it. My spouse will pull his grey hair out. I've grown hundreds of roses, daylilies and many other things from collected, hybridized seed. Are semps easy from seed too? Probably not worse than some of the things I've grown.
