I mean, I wouldn't trust any seeds being bought from a non-brand in China. I thought they are supposed to irradiate biological shipments from other countries? You can get reputable reaper seeds from other sources in the US. I would still recommend buying directly from puckerbutt since they did the work to develop it.
I doubt sketchy seed or plant orders on Amazon follow any sort of proper protocols.
Amazon should not allow these, but are shamelessly callous towards any external risk. A pest coming in on seeds or plant matter can easy become a multi billion dollar agricultural problem.
There is no way anyone should be able to order bootleg plant material with a clean conscience. You save a couple bucks yourself but in the process buy a mega-billions anti-lottery ticket for everyone else.
A whole year down the drain to save a few bucks taught me a lesson about buying quality seeds really quick.
