I really like treestars seed bank, best customer service I’ve ever had and great breeders. Super fast shipping too. Pricey though
Area 51 has always come through for me and they run some killer sales and have a large sale section
Weed guardians family tree is another one I use and have had no problem with
Never had a problem with supreme seed either
All are in the US so no customs and like 4 day shipping.
radogear is another favorite. It’s Cannarado genetics site. I think they only accept cash right now though
Attitude or choice seed bank, same company, have always gotten through customs without a problem but it takes 2-3 weeks to get to your door and shipping is a bit more from the Uk.
Most take Zell,PayPal, crypto. I don’t buy from places that make it hard to pay.
Hope that helps
