^ ok, here you go. I just checked the web pages of czech post and found following:
- international mail economy is for 333 CZK = 12 EUR
- international mail priority is for 433 CZK = 16 EUR
- standard int. parcel 392 CZK = 14 EUR
- priority int. parcel 685 CZK = 25 EUR.
Because I'm not sure, which type of ^ I can use for jeans, you have list above to have overview.
