I had bought 2 packs of onion seeds from the Dollar Tree. Supposed to be 400 mg of seed in each pack. When I opened the pack it didn't look like enough seeds so I counted and weighed them. About 75 seeds per pack and about 200 mg worth in each pack so I got half of what I was supposed to get. The good thing is they were cheap, something like 4 packs for a dollar but still you should get what the package says. I think Walmart sells these sometimes too.
