The launch of a new function on TradeMe has left a number of traders fuming, as they've been unable to complete recent sales or purchases.
It appears the problem have come from a new coding system which allows professional traders to sell more than one item off each auction.
Since the introduction, the site's message boards have been flooded with comments from angry traders - who've discovered a number of issues.
One described how they now can't find expired auctions due to the change and one saying they've got items ready to be sent, but they can't access the addresses of the buyers.
A TradeMe representative responded by saying they're just ironing out a few of the issues.
