"A large proportion of those who shop are members of the loyalty program. I have no doubt that much of the growth is due to increased loyalty from members. I am sure it's an important factor."

Kai Gulbrandsen

CEO, Princess retail chain

"The loyalty program button is on the front page of the cash register, so everything is automatic. Our members use the stamp cards and coupons because it’s so easy to use. We see that we get higher sales from members than non-members."

Evy Ingebrigtsen

Operations and HR Manager, Baker Brun

"Data is the new gold. It is essential that purchase information and customer data form the foundation for all good customer dialogues. Having control over this is in my opinion absolutely crucial."

Pål Wibe

Norway's "Mr Retail" Pål Wibe

"We see that average sales and margins are higher even though we offer a 10% welcome discount. As a customer, you are welcome to bring a little extra in the shopping cart to get the most out of the deal. The goal is for the loyalty program to be the icing on the cake for our customers so that they want to continue shopping with us."

Jon Grøteig Andersen

"When customers shop in our store, we ask them if they want to be members and tell them that they get bonus coupons depending on purchase levels, invitations to events and other benefits. Everyone signs up!"
