I purchased from SLCB this last year. Good communication and shipping was prompt. They were out of town when I ordered, but let me know right away by email that it would be sent in two days (unless I preferred to cancel due to the delay) and it was. The seed quality looked good. The packaging wasn't quite thick enough and the seeds got the crunch from the automatic mail rollers - you know how it leaves all the dimples/holes in the baggies where the seeds were compressed against the side? I gave this feedback and they said they were glad to have the feedback. Anyhow, germination rates were in a reasonable range. The seeds are OP, and 1 out of the 6 varieties I purchased (1 out of 10 total seeds sprouted) was crossed. That's a better ratio than I experienced from any other OP seed provider last year, which seemed like a terrible year for unintended hybrids. My overall opinion was positive and they came across to me as professional and conscientious.
