As part of the agreement, an exclusive CD Wow! offer will appear on the homepage of the Ryanair site each month and a regular promotion from the retailer will be emailed to the 1m consumers who receive updates from Ryanair's shopping service.
Vouchers offering £1 off the retailer's products will be handed out at Ryanair check-in counters to travellers in October and November.
Tony Spillane, managing director of ShopeCentre, which manages the Ryanair online shop, said: "The Ryanair Online shop is all about offering high-quality products at the best prices. CD Wow! has been fantastic in helping us offer the best prices in Europe for CDs, DVDs and games -- and all with free delivery."
Phil Robinson, chief executive of CD Wow!, added: "Our agreement with Ryanair marks yet another step in our commitment to providing customers with the best-value entertainment online, along with a highly personalised and efficient service."
