Hello, I´m from Finland and as I am reading Markku Purho´s site right now, it seems that there are stores in Helsinki, Kouvola and Tampere (Hopefully im not misreading). Personally I always order my stuff from Purho´s site.
Editing a bit: Actually those stores might be only carnival stores selling costumes, wigs and stuff but again I might be wrong. Anyways the online magic shop is great. I hope that helped.
