Staples Online Login

I'm trying to sign into the Staples Business website. I have the user ID and password, but how do I obtain the account number?

The instructions are available on the Order Office and Other Supplies page. That page is displayed when you go to LCR > Reports > Order Office Supplies. That link is in the Unit Information section of the Reports menu. When I use the link to Staples Business Advantage from that page I do not need to enter an account number. I just tested the log on and I only had to enter the user ID and password. The Customer ID provided in step 2 of the Order Office and Other Supplies page is the account number.
