Hi!
Maybe there is a bit of inconsistency when using 'winkel' or 'shop'. If you click on a listing, it says 'vergelijkbare items in deze shop' and 'winkeleigenaar' en 'winkelvoorwaarden'. I would choose to call everything either 'winkel' or 'shop'.
I tried to search a Dutch province, such as Noord-Holland or Drente, but those do not work yet ;). However, I agree that that would be extremely local.
When you enter a new location, the page is not completely translated yet. The text above says: ' Doorzoek 2,181 items in Alle items in Rotterdam, The Netherlands.' This could be ' in Rotterdam, Nederland'. By the way, in the Netherlands we use dots and comma's the other way around. So 2.181 would be two thousand one hundred eighty one, whille 2,18 would be two and eigtheen cents.
I will check back here later!
