Recently Ukash started to sell ukash vouchers in Primera shops across the country. Pay with cash to get your voucher there.

Employees at Primera in the Netherlands are probably just as well informed as their UK counterparts at paypoint. So you will probably have to tell them where to click on their sales terminal (yes, they DO sell it, even if they say they don't).
I must admit i have not yet bought one, but I have tried to do it a couple of times (last time was a few weeks back, when they were still having some technical issues, should be solved now).
Tell them you want a ukash voucher
They say they don't know that and dont sell it
Tell them they have to push the emoney button on the black voucher sales terminal
Then push the Ukash button
They will probably (hopefully) read the screen and ask you for how much money you want one.
(Up till here it worked for me, but then a data connection error occured)
If everything works, you will now get a voucher that you can enter at
EU website, or ingame.
Hope it work now, GL!
