An investigation has found that some supermarkets are effectively charging shoppers as much as £666 per kilogram for dried parsley once the price of small jars or packets is scaled up, a sum that outstrips the per-kilo cost of luxury foods such as caviar and truffles. The finding highlights how herbs and spices sold in small quantities can carry a vastly inflated unit price compared with their bulk value, a practice consumer groups have long flagged as a hidden cost for households doing their weekly shop.

The article's supporting detail was not available in the text retrieved, but the core claim centres on comparing the per-kilo price of dried parsley sold in supermarkets against benchmark luxury goods, with parsley coming out more expensive. This chimes with broader consumer concerns about "shrinkflation" and unit pricing tricks in supermarkets, where small packaging can obscure just how costly an item is relative to its weight.
