$12 for shipping probably seems too high, but the last time I shipped some plants I did some calculating of my actual costs to do so, and I was surprised. It cost's me over $1 for gas to go to and from the post office. The postage is now $4.75. PayPal fees are now about $.80. That totals $6.55. If you consider your time worth even $10 an hour, it takes enough time to bring that up to $12. So, I don't consider $12 to be high. I do consider $25 to be high.
