Exhibit 99.3

EMAIL TO CUSTOMERS

To Our Valued Customers:

Earlier today, we announced the exciting news that Interline Brands Inc. has signed a definitive agreement to be acquired by affiliates of GS Capital Partners LP (“GS Capital Partners”) and P2 Capital Partners, LLC (“P2 Capital Partners”).  This agreement represents an exciting opportunity with new partners, while allowing us to remain laser-focused on our goals and capabilities.

GS Capital Partners is one of the world’s leading private equity investors and the fund through which Goldman Sachs invests capital on behalf of its clients and itself in large, privately negotiated transactions.  P2 Capital Partners, a shareholder of Interline, is a leading investment firm that applies a private equity approach to investing in the public market.  Together, they share our vision of delivering a world class customer experience. Simply put, with our new partners we plan to continue to enhance our technology, product bundles, service levels, distribution capabilities and market leadership in each of our end markets. Additionally, without the short-term pressure of public investor expectations, we can continue to invest in our business to better meet your short and long-term needs. Finally, as I hope you know, Interline has thrived in both public and private settings throughout our company’s history.

While we are still very early in this process, we remain committed to ongoing, transparent dialogue and will provide you updates as appropriate.  In the meantime, it is business as usual - delivering outstanding value to you remains our number one priority, and none of our priorities, commitments or team members have changed.  Since we will continue to operate exactly as we always have, you can continue to expect the same high quality of products, services and professionals.

We have never been more excited about the prospects and capabilities of our Company.  We have great brands and a terrific team, with some of the best sales professionals in the business, and we plan to continue to execute on our strategy to provide world class products and service to our customers.

Thank you for your continued business and loyalty.  We look forward to an even brighter future together.

Sincerely,

Michael Grebe

Chairman and Chief Executive Officer

Interline Brands, Inc.
