I have not, but I've purchased wholesale from Canada,. and also talked to a DG member Ginny, who brings plants across. She lives in Canada, and brings them across to the US to mail.
She is Inanda on DG and Cubits, if you ever need to talk to her. She's pretty knowledgeable.

Actually I wanted to get Omoshiro also, and tried to find it wholesale. No go.
