Hi Alex,
If you are still in the market for some zinnia seeds, I recommend the mailorder firm GeoSeed
https://geoseed.com/. GeoSeed does not have an online store, but they sell the "old-fashioned" way, namely mail-order via a paper order form.
I placed an order with them earlier, and I have some of their zinnia seeds indoors in the seedling stage now. You can order their catalog online. And you can read the online version of the GeoSeed catalog. No pictures, but a very wide selection. Or, if you are in a hurry, most seed companies do have an online store. I already received my Burpee order and have some Burpee zinnias also up in the seedling stage.
This Winter I plan to experiment with triploid zinnias, so I am growing both the normal diploid zinnias as well as some tetraploid zinnias.
