You're right. Good eye.
I changed the fee because other seed swaps are creating a standard of $6. Unfortunately, I don't think $6 is sustainable since some packages can cost over $6 to send, so I compromised and made it $6.50.
This swap was supposed to be one of only two official swaps to begin and this one was going to be the only one that was for *all* seeds. Because of that, I had no idea how many people to expect. If it was a lot of people, I didn't want to lose a bunch of my own money to ship seeds out because shipping cost more than the fee.
