You may use other Dutch stamps , even the stamps like 0.44 € or € 0,39 etc. ( you can buy these stamps by Ebay or Marktplaats . )
If you want to send to " World " , it has to be € 1.50 .
I also do use stamp combinations like 1 stamp ( Dutch ) with the number one = €0,91 .
You can add a stamp : € 0,44
and add 3 stamps , € 0.05
Then you will have € 1,50 , the price of a stamp for International shipping.
( Don’t forget to add the word " Priority " or use a sticker :
The stamps like 0,39 and 0.44 Eurocent are only available by online sellers .
Post. NL . doesn’t sell these stamps anymore .
