Hmm, I don't know exactly what day and time that you ordered but here's some relevant info.
From their website, "Seed orders are sent out within 3-5 business days of receipt. We ship seeds via U.S. Postal Service year-round to the U.S. and Canada."
"Business days" would not include Saturday, Sunday, or this Monday since it was Columbus Day. Once shipped, then you would need to factor in the extra days that it takes the USPS to transport them to you.
If you are concerned, then you should contact them. They are a legit company with a good reputation. When I ordered a few plants, they quickly replaced one that was having issues after I emailed them about it.
I hope that you get your seeds soon!
