I have ordered from Happy Green Shop three years in a row. Their prices are great and I love that they ship via mail snail mail. I'm in Canada and it's cheaper to order from Ireland than from our neighbourhood to the south.
The seed quality is excellent. I've had no problems with germination and the resulting plants have been strong and healthy.
I appreciate the extra seeds that they send as a thank you. I've discovered things that I never thought to grow!
The one time that I had to contact customer service they responded immediately and satisfactorily solved my problem.
I will continue to order from them as long as I continue to garden.
