Premier is celebrating its 20th birthday with a host of promotional activity themed around the number 20.
Shoppers stand to win a share of £20,000-worth of prizes for every promotion, and 20 prizes will also be available for retailers to win.
The Premier Mega Deal will also move to four deals each promotion to help retailers drive more sales and profit, Premier director Martin Swadling said.
The first promotion that offers four Mega Deals includes 15 pack Carling, Strongbow and Fosters for £10 and Pampers at £2.99.
“We have a whole host of exciting plans to celebrate Premier reaching our 20th birthday,” Swadling said. “This includes some fantastic ways to increase footfall, sales and importantly profit.
“I am sure throughout the summer we will give our retailers some fantastic opportunities to create a real buzz in their stores and give shoppers another reason to visit them.”
