I will attest to the negative experience, from quality of plants to prices to customer service. This is based on two purchases, one year apart. Not 100% bad plants, but 50% good isn't good.
The 30 day not repotting thing made no sense to me, until I realized it makes sense to them. If you repot sooner and have a problem, they can say "we told you to wait." If you wait, and then repot and find they shipped you a plant with 90% dead roots, they can say "well they were fine when we sent it."
Which is not the case. I repotted phrags from Norman's when I got them - supposedly full-size, ha! - and the roots were dead on arrival.
No more Norman's for me.
