Buying karma koin cards online?

So coming from a country where they dont sell karma koin.When i occasionaly want to buy nx cash i have to wait till we go on vacation to florida or i have to buy them of amazon, but recently the prices for the cards have gone up (64 dollars for 50k nx).So do you guys know any other good sites i can buy karma koins perhaps cheaper than amazon?

Thanks in advance
