True, but someone just getting started with seeds can buy a few large packets very cheaply, split and offer those in a swap, and bring home greater variety than the same amount of money would have bought from a seed vendor. That's what I did for my first big seed swap (Ella's Hog Wild Piggy Swap).
Admittedly, postage for a swap might be as much as $12 (for sending plus receiving). And that could be 4-6 pkts from a website with free shipping. But I brought home 53 items from Dave's recent ATP Beta Swap. And that was a swap with no theme. That's around 23 cents per trade packet, not counting the cost of seeds I sent (83 packets).
