I've ordered once from all these, got my orders delivered to the US in a timely manner, and they all germinated at an acceptable rate:The Single Seed Centre (my go to if I want singles, but a bit expensive)Herbie's Head ShopOASeeds (usually cheapest prices I can find)
Attitude, James Bean and Great Lakes have been good for me.
