Yeah I tend to order ESP8266 devices and random sensors, from AliExpress. Although the postage often takes 3-8 weeks its a little hit and miss whether the packets are delivered or have to be collected.
Mostly these days I tend to use verkkokauppa and similar "local" shops that can be collected from.
I like SmartPosti parcel boxes as well, especially how I can select the delivery target that most suits my route and schedule. I usually use one that's close to my work in a mall so I can do some groceries while getting my packages.
