If I may add my 2 cents.
I did not see this listed, a site that may be of interest is
www.artisticgardens.com. I don't know too much about them but
they have 35 cent seed packet samplers and they have a lot of "non-standard" fare. I heard about them from a radio gardening show and figured I would give them a shot. It did take a while to receive the order but it did arrive.
I just started the seed a couple of days ago so nothing has sprouted as of yet so I have nothing to report.
I figured someone may be looking to try some new varieties for a low cost or get the 35 cent packet and save seeds from the plants for next year.
And I just used a coupon from Garden's Alive for $25. No minimum order and no shipping if the total cost of product and shipping is less than $25.
It pays to get on mailing lists.
