Hey, I'm currently in Finland and I'll be heading to London in two weeks -- just wondering if anyone can recommend any electronics stores that would carry Arduino products (lilypad components, specifically). I was thinking to order something online and have it shipped here, but then it occurred to me that I'll be in London where I could most certainly find somewhere that sells components.
No, really, I don't know anywhere, but then, London's a pretty big place.
If you're after components, then there are lots of Maplin stores, but I don't know any specialist Arduino stores.
I don't think there is any store anywhere in the world where you can go in and buy Arduino's or shields. They are all (or mostly) online stores.
As for components the only option you get really is the very expensive Maplin's store.
Most online stores are very quick at getting stuff out to you. If you are in London a few days then make your order before you fly and by the time you get there it will have arrived.
