Where can I buy TWR?

Hey there! I have recently been getting into Thomas Wooden Railway, and want to start collecting and building up a layout. Because I'm located in Northern Norway, it's really difficult to find people selling used items, finding TWR (not Thomas Wood, even though that's rare here too) in stores and second hand shops. I keep constantly looking online on a Norwegian buy and sell website called Finn, facebook marketplace, and asking people around me if they have any items they wanna give or sell to me.
I have been looking on Ebay, but the shipping and handling prices are ridiculous because I live so far away from the US (where most of the listings I've found have been located).

Basically, I was wondering if anyone had any tips for places online where I could find reasonably priced TWR items, where the cost of the items/sets themselves, as well as the shipping don't break the bank. I'm really excited to hopefully become a part of the TWR community, and hoping you guys will be nice to me too!
