Swiss retail giant Migros is offering customers a CHF10 (US$10.20) voucher if they can find a product underselling the co-operative’s core range of 302 lines.
After promising to offer the cheapest price in the country on these items, the retailer has set up a telephone hotline for consumers to police rival aisles.
Callers in Switzerland can contact 0848 84 0848 or email m-infoline@migros.ch if any national retailer can beat the Migros price.
The claim will be checked “immediately” and store prices will be lowered “as soon as possible”, the retailer said.
