Depending on how many you are looking for I recently ordered some from ebay. I got 29 different types of seeds & it tells you how many are in each packet but it said it's about 2500 seeds total for $10. I figured it was worth the $10 to try them since seeds can get to be expensive. I sent the link to them & most people will alter then & give you more of some than another or sell you certain kinds. We do a large garden so I was going to get these & see how they look & then contact them for more if certain ones. Hope that helps you.
As odd as it sounds I bought a bunch of seeds for my husband for christmas. I found Mountain Valley Seeds to be a great place to buy in bulk but I also orded some trees off ebay, 2 dwarf cherry trees, 2 dwarf trees & 25 colorado blue spruce christmas trees & the total with shipping was $24. You can't beat that. I plan on getting more in the near future. http://www.mvseeds.com/index.html You
I have ordered from Baker Creek and plan to order from Fedco. They have a non-GMO guarantee on their seeds, which is so important nowadays. I had wonderful results with Baker Creed seed.
