Ladies and Gentlemen:

         We are acting as counsel to Intellesale.com, Inc., a Delaware
corporation (the "Company"), in connection with the issuance and sale by the
Company of up to 4,600,000 shares (the "Company Shares") of its common stock,
par value $0.01 per share ("Common Stock"), and the sale by Applied Digital
Solutions, Inc. (the "Selling Stockholder") of up to 1,955,000 shares of Common
Stock (the "Stockholder Shares") as contemplated by the Company's Registration
Statement on Form S-1, File No. 333-87043 (as amended, the "Registration
Statement"). The Company Shares and the Stockholder Shares are proposed to be
sold on the terms and conditions to be set forth in an underwriting agreement,
by and among the Company, Ladenburg Thalmann & Co. Inc. and Punk, Ziegel &
Company, L.P. as representatives of the several underwriters named therein (the
"Underwriting Agreement").

         In connection therewith, we have examined and relied without
investigation as to matters of fact upon the Registration Statement,
certificates of public officials, statements and certificates of officers of the
Company, and originals or copies certified to our satisfaction of the Amended
and Restated Certificate of Incorporation and Amended and Restated Bylaws of the
Company, minutes of meetings of the Board of Directors of the Company and such
other corporate records, documents, certificates and instruments as we have
deemed necessary or appropriate in order to enable us to render the opinions
expressed below.

         In rendering this opinion, we have assumed the genuineness of all
signatures on all documents examined by us, the authenticity of all documents
submitted to us as originals and the conformity to authentic originals of all
documents submitted to us as certified copies or photocopies.

         Based on the foregoing and in reliance thereon, we are of the opinion
that:

                  (i) the Company Shares are duly authorized and, when issued
         and delivered to the underwriters against payment therefor in
         accordance with the terms set forth in the Underwriting Agreement, will
         be validly issued, fully paid and nonassessable; and

                  (ii) the Shareholder Shares were duly authorized and validly
         issued by the Company, and are fully paid and nonassessable.

         This opinion is not rendered with respect to any laws other than the
laws of the State of Delaware and the federal laws of the United States of
America, each as in effect on the date hereof.

         We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the prospectus filed as a part thereof. We also consent to your
filing copies of this opinion as an exhibit to the Registration Statement with
agencies of such states as you deem necessary in the course of complying with
the laws of such states regarding the offering and sale of the Company Shares
and the Shareholder Shares.


                                Very truly yours,

                                /s/ Bryan Cave LLP
