Amoy is shrinking the packs of its stir fry sauces to bring the price under £1.

The new packs are down from 150g to 120g, serving two people rather than three. The price has been cut from £1.19 to 95p.

"Research shows the 95p price provides the optimum growth opportunity," said brand manager Caroline Grimshaw. "It encourages shopper loyalty and repeat purchases."

The seven-strong range, which is being relaunched in printed aluminium pouches to align it with the rest of the Amoy portfolio, will also gain from two new variants, Thai Sweet & Sour and Pad Thai Stir Fry.
