I ordered from Claire Austin, they contacted me to say that they felt one of the plants I'd chosen wasn't of sufficient quality to send out in their opinion, and did I want a refund or change it for another variety.
Their plants are not cheap really and I really appreciated their honesty and integrity in not posting out a plant that didn't pass muster. It's a major downside of buying online when you cannot choose the exact specimen from the stock available. (Sometimes you look at the plants sent out and think "I wouldn't have picked this one, it's a weird, lopsided shape" or similar...)
