BJ's Wholesale Club is a leading warehouse club operator on the east coast of the United States. We deliver significant value to our members, consistently offering 25% or more savings on a representative basket of manufacturer-branded groceries compared to traditional supermarket competitors. We provide a curated assortment focused on perishable products, continuously refreshed general merchandise, gasoline and other ancillary services to deliver a differentiated shopping experience, that is further enhanced by our omnichannel capabilities.
Over the last three years, we have hired Chris Baldwin as Chairman, President and Chief Executive Officer and have made multiple senior management hires and changes, adding consumer packaged goods, digital and consulting experience to our leadership team. This new leadership team has implemented significant cultural and operational changes to our business, including transforming how we use data to improve member experience, instilling a culture of cost discipline, adopting a more proactive approach to growing our membership base and building an omnichannel offering oriented towards making shopping at BJ's more convenient. These changes have delivered results rapidly, evidenced by positive comparable club sales over the last six quarters and net income growth of over 150% and adjusted EBITDA growth of 8% in aggregate form from fiscal year 2017 to fiscal year 2018. In fiscal year 2018, we generated total revenues, net income and Adjusted EBITDA of $13.0 billion, $127.3 million and $578.4 million, respectively.
Since pioneering the warehouse club model in New England in 1984, we have grown our footprint to 216 large-format, high volume warehouse clubs spanning 16 states. In our core New England markets, which have high population density and generate a disproportionate part of U.S. GDP, we operate almost three times the number of clubs of the next largest warehouse club competitor. In addition to shopping in our clubs, members are able to shop when and how they want through our website, www.bjs.com; our highly-rated mobile app and our integrated Instacart same-day delivery offering.
