While I did not actually 'trade' with Jim, he offered up sharing some nice extra seedlings (he called them) in exchange for postage.
Upon receipt of postage from me,
he acknowledged receiving the stamps,
kept me updated about when he would dig and ship (had numerous ones to send to,
packaged them well,
notified me that they were on their way, complete with confirmation number.
What I expected were frail seedlings, but what I got was a 1 LB box of well rooted plants.
Jim is a wonderful sharer!
