Fortunately I do not buy much seed but I do like to browse . Menard's and Wall Mart have the seed racks out .Sounds like there may be another seed shortage this year, so if there's something you just gotta have, you might want to order online.
Last spring my local feedstore/greenhouse had hardly any started herbs for sale because they weren't able to buy seeds for starting their plants.
I am happy to say mine are all germinating in the window as I type. Except the rosemary, but it's only been a week, and rosemary can take a while.
