Killer Tomato

for tomato seeds try tomatoville.com to find reputable suppliers. They often have small seed counts and lots more than tomatoes.
I bought almost all of my seeds from "heirloomseedguy" on eBay last year. Excellent germination, and lots of varieties that I can't find anyplace else. If you buy 20 different things, the shipping is free. He has heirloom and regular (which were cheaper).
The only problem I had was that my Sungold tomatoes were not Sungolds, but some regular ol' cherry tomato. Prolific, but not what I wanted. The Costoluto Genovese (my favorites) were amazing. The Polish Paste were fussy lil' SOB's, and I wasn't impressed -- I've grown better Romas. Not the seed guy's fault, I'll blame my poor soil.
He has a great variety of cabbages, kales, broccolis too.
