In its first competitive push since its takeover by Select Retail Holdings, Superquinn had announced that customers spending E65 in its stores in the run-up to Christmas would be given a discount voucher worth E100. Tesco responded by saying it would accept the rival vouchers, many of which relate to products on its shelves.
But this week it was forced to backtrack, saying it was unable to accept the vouchers after all. A Tesco spokeswoman said there was a technical problem relating to differences in barcoding.
Superquinn chief executive Simon Burke said the vouchers had been designed with such a scenario in mind. “It’s great that an Irish minnow can so wrongfoot a huge multinational.”
