The grocer said on Friday the price of the deal, which typically brings together a sandwich, a packet of crisps and a soft drink, will from Oct. 24 go up from 3 pounds ($3.34) to 3.40 pounds for members of its Clubcard loyalty scheme.

Tesco said over 70% of its customers currently use a Clubcard when buying a lunchtime meal deal.

The price of the deal for those without a Clubcard will go up from 3.50 pounds to 3.90 pounds.

Shoppers have been hammered by rising food inflation, which hit a record 13.9% in September, according to industry data.

Tesco, which is facing extreme cost headwinds, particularly energy, labour and currency, says it is "inflating a little bit less and a little bit later" than competitors.

Earlier this month it forecast full-year profit at the lower end of its previous guidance, blaming uncertainty over how consumer spending will evolve amid a worsening cost-of-living squeeze.

Tesco said a number of meal combinations would cost more than 6 pounds if purchased separately.

In July, McDonald's hiked the price of its cheeseburger for the first time in 14 years.
