In reply to GraB:
I've seen the website from time to time for ages, but only just looked up their actual shops. I used to browse in their Helsinki shop regularly but didn't often find it the cheapest option and now realise their Vantaa shop is the one just round the corner from where my kids went to school when we still lived there! That had the feeling of being like an outlet store and I definitely bought stuff there at good prices.
It's 5 and a bit years since I left Finland and I'm sure back then they were called something else - HeMa will probably remember - so didn't realise they were the same as the webshop. Anyway, definitely a proper long standing business, but haven't bought from their website.
Now feeling nostalgic about wandering around Helsinki back in the 90s, as a recently arrived immigrant, window shopping and killing time between teaching English in various offices and factories around the city!
