Dear Mr. Niethamer:

Alliance Data Systems Corporation, a Delaware corporation (the “Company”), is in receipt of the letter dated October 30, 2008 from the Securities and Exchange Commission Staff (the “Staff”) relating to the Company’s Form 10-K for Fiscal Year Ended December 31, 2007, Form 10-Q for Fiscal Quarter Ended March 31, 2008, Form 10-Q for Fiscal Quarter Ended June 30, 2008, and definitive Proxy Statement on Schedule 14A filed on April 24, 2008, each filed with the Securities and Exchange Commission (the “Commission”) (the “Comment Letter”).

Per your instructions to counsel for the Company, this letter will confirm that the Company will submit its response to the Comment Letter after November 13, 2008, but on or before December 12, 2008. The additional time will enable the Company to accommodate the regular quarterly meetings of the Company’s Board of Directors, Audit Committee and Compensation Committee scheduled for December 9 and 10, 2008, and will allow for coordination of the Company’s response with the Company’s independent accountant and compensation consultant.

In its response, and as requested by the Staff in the Comment Letter, the Company will address the Staff’s comments and provide a written statement acknowledging that:

If you have any questions with respect to the foregoing, please call me at (972) 348-5191 or the Company’s Executive Vice President and General Counsel, Alan M. Utay, at (972) 348-5677.
