As part of the Metro Group, which also owns electronics giant Media Markt, Media World is Italy's largest retailer, with almost 13 percent of the consumer electronics retail market in the country.
Dell sells its products in Saturn stores in France, which is also under the Metro Group umbrella.
"We've made a lot of progress on our multi-channel sales strategy in the past 18 months, but we're really just getting started," said Michael Tatelman, VP sales and marketing Dell global consumer business.
"Whether people shop and buy online, over the phone or in our stores, we're getting some great momentum in the consumer electronics space and looking forward to making it easier for more people around the globe to get what they want from Dell."
This year most of Dell's store expansion has taken place in China, followed by Europe, other countries in the Asia-Pacific region and Latin America.
Dell is also expanding its partner strategy to include the telco industry as a new channel to reach people.
The company has forged agreements with Verizon and AT&T in the U.S., Vodafone in Europe, China Mobile in Asia and other qualified telco partners in India, Japan and Europe.
