                                PRELIMINARY NOTE

     This Schedule 13D amends and supercedes the Schedule 13D originally filed
by Mr. Pratt and Mr. Gale on August 19, 2005, and amended on December 13, 2006,
to reflect transactions on and developments through December 6, 2007, inclusive,
relating to such persons' respective holdings of the securities and issuer named

     Mr. Pratt is the sole Manager of Gratco, LLC ("Gratco"), a limited
liability company whose membership interests are held by irrevocable trusts (the
"Trusts") of which Mr. Pratt was the grantor. Mr. Gale is the sole owner,

trustee of the respective Trusts. The sole voting member of Gratco is the David
C. Pratt Irrevocable Grantor Retained Annuity Trust, dated 12/1/92, (the

could be deemed to constitute a "group" with respect to Gratco's and Calco's
respective beneficial ownership (as defined in Rule 13(d)-3 under the Securities
Exchange Act) of the Registrant's securities and accordingly jointly file this
Schedule 13 D. Mr. Pratt and Mr. Gale are not related by blood or marriage.

     (d)  no such convictions.

     (e)  not a party to any such proceedings.

     (f)  United States.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     Prior to the transactions reported herein, and as previously reported, the
GRAT was the economic owner of 1,400,000 shares of Registrant's Common Stock and
Gratco was the economic beneficial owner of 5,701,255 shares of Registrant's
Common Stock.

Stock Purchase

     On December 6, 2007, Gratco entered into a stock purchase agreement (the
"Stock Purchase Agreement") pursuant to which it agreed to purchase 3,065,000
shares of the Registrant's common stock (the "Shares") for an aggregate purchase
price of $18,083,500 million, or $5.90 per share (the "Stock Purchase"). The
closing market value per share of the Registrant's common stock on December 5,
2007, was $4.70.

     The purchase price for the Shares was payable from cash held by Gratco,
including funds arising from capital contributions and borrowings from its
existing members. In order to provide short-term assistance in funding such
investments in Gratco, Mr. Pratt is providing an interim loan to the GRAT of
approximately $10.0 million. Such loan will be repaid to Mr. Pratt following
liquidation of unrelated assets held by the GRAT. None of the Shares are pledged
to third parties in connection with such arrangements. The closing and funding
of the purchase and issuance of the Shares occurred on December 5, 2007. A copy
of the Stock Purchase Agreement was filed as Exhibit 10.2 to the Registrant's
Current Report on Form 8-K dated December 6, 2007, and is incorporated by
reference into this Item 3.

     The Registrant provided certain registration rights to Gratco under the
Stock Purchase Agreement. Under the Stock Purchase Agreement, the Registrant has
agreed to file a shelf registration statement for resales of the Shares within
365 days of the closing date of the Stock Purchase. The Registrant is further
obligated to use its best efforts to cause the shelf registration statement to
become effective under the Securities Act of 1933 within 420 days after the
closing date of the Stock Purchase (480 days in the event of a full review of
the shelf registration statement by the Securities and Exchange Commission).

ITEM 4. PURPOSE OF THE TRANSACTION.

     The purpose of the transaction was to provide a significant portion of the
funding required by the Registrant in connection with the Registrant's
acquisition of all the outstanding equity securities of Overton's Holding
Company as more fully described in the Registrant's Current Statement on Form
8-K dated December 6, 2007. In addition to the funding provided hereby, Mr.
Pratt individually guaranteed a portion of the indebtedness incurred by the
Registrant in connection with its acquisition of Overton's Holding Company. (See
Item 2.03 of Registrant's Form 8-K dated December 5, 2007.)

     The acquisition of the Stock by Gratco was undertaken for general
investment purposes. Mr. Pratt or Gratco or the GRAT may, from time to time,
acquire additional shares of stock or participate in financing transactions
relating to the Registrant or may determine to sell portions or all of the
investments currently held. No transactions undertaken by Mr. Pratt or by the
Trusts were undertaken with a view to changing or effecting any of the events
listed or described in items (a) through (j) of Item 4, notwithstanding the fact
as reported above that Mr. Pratt was elected to a newly-created vacancy on the
board of directors of the Registrant coincident with the investment made by the
GRAT in August 2005.

     Although Mr. Pratt did not join the Board of Directors with a specific
transactional agenda, his position as Chairman of the Board of Directors of the
Registrant and the percentage of ownership of the Registrant held by Gratco and
the GRAT enable him to exercise substantial influence over the policies,
practices and

direction of the Registrant's business. It is Mr. Pratt's expressed and
continuing intention to work with the Registrant's management team to assist in
realizing the growth potential he perceives in the Registrant.

Notes:

(1)  Based upon 24,429,894 shares outstanding following the transaction reported
     herein and a sale by the Registrant of an additional 1,002,797 shares on
     similar terms to Holiday Superstores, Inc. (an affiliate of Ronald A.
     Erickson, the Registrant's Vice Chairman, and of Gerald A. Erickson, a
     Director of Registrant).

(2)  Exercisable options; does not include options, not presently exercisable,
     to purchase an additional 10,000 shares. Options granted under Registrant's
     option program for non-employee directors.

(3)  Includes shares held by Gratco and 1,400,000 shares held directly by the
     GRAT. Although Mr. Gale, neither individually nor as the controlling person
     of the trustee, participates in the management of Gratco, the fact that
     trusts indirectly controlled by Mr. Gale hold all the equity interests in
     Gratco may be deemed to result in shared voting or dispositive powers with
     respect to shares held by Gratco.

(4)  The GRAT is the sole voting member of Gratco LLC. Except to the extent
     reflected in paragraph (d) below, neither Mr. Pratt nor Mr. Gale has any
     economic interest in any of such trusts.

AS PERMITTED IN S.E.C. REGULATION Section 240.13D-4, THIS STATEMENT SHALL NOT BE
CONSTRUED AS AN ADMISSION THAT DAVID C. PRATT IS, FOR THE PURPOSES OF SECTION
13(D) OR 13(G) OF THE SECURITIES EXCHANGE ACT, THE BENEFICIAL OWNER OF THE
SECURITIES HELD BY THE DAVID C. PRATT IRREVOCABLE GRANTOR RETAINED ANNUITY
TRUST. MARK R. GALE DISCLAIMS ANY ECONOMIC BENEFICIAL INTEREST IN THE ASSETS OF
GRATCO OR THE DAVID C. PRATT IRREVOCABLE GRANTOR RETAINED ANNUITY TRUST.

     (b)  Subject to the above disclaimers of beneficial ownership, for each
          Reporting Person named in paragraph (a), the number of shares reflects
          shares as to which the Reporting Person holds sole voting and
          investment power.

        SECURITIES OF THE ISSUER.

     As indicated above in this Schedule 13 D, David C. Pratt serves as a
director of the Registrant. As a director of the Registrant, Mr. Pratt may be
entitled to indemnification in accordance with applicable law and the
Registrant's by-laws.

     The Stock Purchase Agreement also contains cross-indemnification provisions
between Gratco and the Registrant and usual and customary terms relating to

Stock by such holder.

     As indicated in Item 3 above, any description herein of provisions of the

text and terms of such agreement.

     The GRAT and Gratco may agree to a further contribution by the GRAT to the
capital of Gratco in the form of a contribution of the 1,400,000 shares of
Registrant's Common Stock in exchange for additional ownership interests in
Gratco.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.
