Hungary's Competition Office (GVH) on Monday said it fined supermarket chains Tesco, Spar and Cora a combined HUF 14m for misleading advertising.
GVH fined UK-owned Tesco's Hungarian unit HUF 10m for not stocking enough of discounted products advertised in its fliers.
Spar was fined HUF 1m for not stocking discounted items it advertised as well as for claiming products were offered at a discount when they were not.
GVH fined Cora HUF 3m for failing to comply with instructions it gave the company as the result of an investigation in October that found stores did not inform bicycle buyers they had to pay extra for a warranty.
