I bought two of these when they were on sale, one for the shelf in the basement and one to plant to ensure the seeds actually "work." And they do.
What I planted: Beets, spinach, lettuce, carrots, green beans (Zone 4). This was my first ever garden and I have no mentor for this endeavor, so I'm especially happy to report that these items all came up when I planted them as directed. The varieties enclosed taste wonderful and survived my hamfisted attempt at gardening. I'm confident they'll be even better next year when I plant them and actually have some idea what I'm doing.
The packaging is superb. If you count the can they come in, many of these seeds are triple sealed by the can, individual Mylar packages, and resealable bags within the Mylar. There is a sheet that gives basic instructions for harvesting your own seeds from your crops and each package has basic planting instructions.
For what comes in the can, the overall price does not seem out of line to me. I would purchase this product again.
