Supermarkets have also hiked prices for a number of seasonal Lindt lines, including a 100g Lindt Gold Bunny - up 15% to £2.75 - and a 260g Lindt Gold Bunny Luxury Easter Egg - which is 10% more expensive at £10 on average in the mults. Thorntons chocolate has also been subject to price rises, with a 151g Thorntons Hopalot white egg up 9% to £3.19 on average, while a 342g Thorntons Lemon Meringue White Chocolate Egg is up 19% to £9.50. Chocolate manufacturers have faced big cost pressures over the past 18 months, with the cost of raw materials such as cocoa beans and sugar surging due to global supply shortages and the impact of the Brexit vote on the pound. Mars last week said it had been forced to shrink some of its sharing bags of chocolate, while keeping prices the same, because it could no longer absorb "rising raw material and operational costs". However, cocoa prices are beginning to ease on the back of an improved supply situation.
