Baker Creek offers 10 seeds for $3.00.

I've noticed that Baker Creek often puts many more seeds into a packet than they promised, but sometimes only a few more.
It doesn't sound like a good place to buy a half-kilo of seed from! They said the seeds were tiny. You might have to save seeds from many plants to get 1/4 to 1/2 kilo.
There are 22 reviews and a link to a long blurb about them:
