There are now more than 50 listings on Trade Me for the chocolate wafer treats, with prices ranging from three dollars to 300.
Pods are no longer available online at Countdown, Pak 'n Save or New World.
Trade Me spokesperson Millie Silvester says this isn't the first time they've seen something like this pop up.
She says when tangy fruits were discontinued, a 10 pack was put up for 100 dollars.
