Cadbury introduced new flavours and changed its packaging of the chocolate treats in September.
Unimpressed customers have been complaining on the company's Facebook page.
And it seems someone in Christchurch feels the same way, listing a box of the chocs on TradeMe as an unwanted Christmas gift.
The seller says they received them from work but are really disappointed with the changes.
69 people have added the chocolates to their watchlist, and ten people have already made a bid, with the current price at six-dollars .
