CDW FINANCE CORPORATION

$600,000,000 5.000% Senior Notes due 2025

Pricing Supplement, dated February 23, 2017, to the Preliminary Prospectus Supplement, dated February 23, 2017 (the “Preliminary Prospectus Supplement”), and related Base Prospectus, dated October 16, 2014 (the “Base Prospectus”), of CDW LLC and CDW Finance Corporation. This supplement (this “Pricing Supplement”) is qualified in its entirety by reference to the Preliminary Prospectus Supplement and the Base Prospectus. The information in this Pricing Supplement supplements the Preliminary Prospectus Supplement and the Base Prospectus and supersedes the information in the Preliminary Prospectus Supplement and the Base Prospectus to the extent inconsistent with the information in the Preliminary Prospectus Supplement and Base Prospectus. Terms used herein and not defined herein have the meanings assigned to such terms in the Preliminary Prospectus Supplement and the Base Prospectus.

The aggregate principal amount of notes to be issued in the offering increased from $500,000,000 to $600,000,000. The increased amount of $100,000,000 will be used to correspondingly reduce the amount of borrowings under ABL Facility being utilized (a) to fund the redemption of $600.0 million aggregate principal amount of our 2022 Senior Notes, representing all of the 2022 Senior Notes currently outstanding, at a redemption price of 100% of the principal amount redeemed plus a “make whole” premium, and accrued and unpaid interest to the date of redemption, and (b) to pay fees and expenses related to the redemption and this offering. The information in the Preliminary Prospectus Supplement (including, but not limited to, the financial information in the capitalization table and use of proceeds) is deemed to have changed to the extent affected by the increase in the size of the offering of the Notes.

(2) the then-outstanding principal amount of the Note.

Trade Date: February 23, 2017

Settlement Date: March 2, 2017 (T+5)

It is expected that delivery of the notes will be made against payment therefor on or about March 2, 2017, which will be the fifth business day following the date hereof (such settlement cycle being herein

referred to as “T+5”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the date that is three business days preceding the settlement date will be required, by virtue of the fact that the notes initially will settle T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade the notes prior to the date that is three business days preceding the settlement date should consult their own advisor.
