Regional Online Stores
From Redump Wiki
An online game purchasing guide. On eBay sometimes games only appear on regional sites, even if you search "Worldwide" from your region. This often means they will only ship within their own country however, so you might need someone else to receive them in the country of sale.
Also use eBay Advanced Search to search specifically within one country. 
- geo-ship.com: Aggregates data from all regional eBays. It is much more thorough than searching "worldwide" on eBay, due to eBay's limitation of what can be seen from regional variants as a result of seller shipping options.
Czech Republic / Czechia
Norway There is not much of a market for used games in Norway it seems.
- taobao.com - lots of Japanese protos pop up here
