Elton, the swaps aren't for buying seeds, but this site does have a classifieds section here:
http://garden.org/forums/view/...
Most of what is listed there right now are plants, but I think there are some seeds.
What type of seed are you looking for? I might be able to provide better assistance if I knew what you wanted. (For instance, I was selling daylily seeds just recently.) Or, if you're looking for other types of seeds, I might know some vendors to recommend...
