Hi OzBud...My guess is that they're clearing out last year's stock of seed. I buy 90% of my seeds from Bonza or Herbie's. They both have a good selection of seeds with decent prices and reasonable shipping, take U.S. credit cards, and guarantee delivery, which is why I use them. They both usually have very good freebie seeds with an order (no freebies for this Bonza 25% off sale though). Never lost an order from either one. I sometimes buy regular Green Crack seeds from Beaver Seeds in Canada (only place I've found G.C. regular seeds). No problems with them either. Lost only one order, that was from ILGM a couple of years ago. They replaced it without a problem. ILGM sells a strain they developed called "Gold Leaf" that you can't get anywhere else. It's a beautiful plant, smells and tastes like nothing else, and has a great buzz. He's not saying what the genetics are.
Anyway, just thought somebody here might be looking for a good deal on some good seed.
BTW...seeds stored in a sealed container in the fridge will be viable for years.
