Samlav,
First of all, it's called "Not from the Seed Rack Seed Swap" so I assume the primary emphasis would be seeds you or someone else has harvested. I have no problem with commercially bought seeds either though. I'm frugal as well. My thought in joining was that I could get several different varieties of seeds for what I would spend on a couple of seed packets or even one clearance plant. It seems to me for the price of admission, there's really no way to lose. I get to share my excess seeds with others and vice versa.
Second of all, I would imagine everyone's wish list is longer than their offering list. I have over 200 on my wish list and 60 on my offering list. While I'm interested in all those, I know I won't get a lot of them. Several of yours are on my wish list. I think you've got a pretty good list going. I look at my seeds to see if anyone has added them to their wish lists but have no idea if they put one star or five.
I think it's going to be lots of fun. And in the end will be much cheaper than smaller individual trades on other sites. That's just my two cents worth and since I'm frugal too, that's about all I'm willing to spare!
