Exhibit 99.1

99¢ ONLY STORES® COMMENCES CONSENT SOLICITATION

CITY OF COMMERCE, California — September 18, 2013 - 99¢ Only Stores® (the “Company”) announced that it commenced a consent solicitation (the “Solicitation”) with respect to proposed amendments (“Proposed Amendments”) to the indenture (the “Indenture”) governing the Company’s outstanding $250 million in aggregate principal amount of 11% Senior Secured Notes Due 2019 (the “Notes”).

The Proposed Amendments would (i) eliminate the leverage ratio test currently required to make a permitted Restricted Payment under the Indenture for the purpose of funding the obligation to repurchase shares pursuant to the Rollover Investor Put (as defined in the Indenture) and (ii) expand the definition of the Rollover Investor Put to include the Purchase (as defined below).

The Company’s parent, Number Holdings, Inc. (“Parent”), is in discussions to enter into an agreement with certain former members of the Company’s management, Eric Schiffer, Jeff Gold and Howard Gold, and Karen Schiffer and The Gold Revocable Trust dated October 26, 2005 or certain of their affiliates (collectively, the “Sellers”) under which (a) Parent will purchase from each Seller all of the shares of Parent’s Class A Common Stock, par value $0.001 per share (“Class A Stock”), and Parent’s Class B Common Stock, par value $0.001 per share (“Class B Stock”), owned by such Seller and (b) all of the options to purchase shares of Class A Stock and Class B Stock held by such Seller will be cancelled and forfeited, for aggregate consideration of approximately $130 million (the “Purchase”).  The Company is seeking consents (the “Consents”) of the Holders (as defined below) for the Proposed Amendments to ensure that the consummation of the Purchase would be permitted under the Indenture.

The record time and date to determine holders of the Notes entitled to consent (the “Holders”) is 5:00 p.m., New York City time on Tuesday, September 17, 2013. The Solicitation will expire at 5:00 p.m., New York City time, on Thursday, September 26, 2013, unless extended (the “Expiration Time”). As part of the Solicitation, subject to the satisfaction of the terms and conditions of the Solicitation, the Company will make a cash payment (the “Consent Payment”) equal to $2.50 per $1,000 in aggregate principal amount of Notes, in respect of which a Consent has been delivered in accordance with the procedures described in the Consent Solicitation Statement (the “Statement”) (and not revoked) at or prior to the Expiration Time.  Consents may be revoked at any time prior to the date that the Proposed Amendments become effective.  The Company’s obligation to make the Consent Payment is contingent upon, among other things, (i) receipt of Consents from the holders of a majority in aggregate principal amount of the Notes at or prior to the Expiration Time, (ii) execution of a supplemental indenture, (iii) the execution of an amendment to each of the Company’s term loan and ABL credit facilities to permit the restricted payments and the additional borrowings under the term loan credit facility necessary to consummate the Purchase, (iv) the consummation of the Purchase substantially concurrently with or subsequent to the effectiveness of the Proposed Amendments and (v) other customary conditions described in the Statement.  The Consent Payment will become payable upon execution of the supplemental indenture containing the Proposed Amendments, and will be paid promptly following the later of the Expiration Time and the satisfaction or, where applicable, waiver of such conditions. The Company has not yet entered into, and may not enter into, an agreement to effect the Purchase.

Holders may obtain a copy of the Statement and related material from the information agent, D.F. King & Co., Inc., at (800) 967-4607 or (212) 269-5550 for banks and brokers.

The Solicitation is not being made to, and Consents are not being solicited from, Holders in any jurisdiction in which it is unlawful to make such Solicitation or grant such Consent.
