The official Menards website, Menards.com, publishes the company's catalog as of 2015. To access it, click on the Weekly Ad tab on the top of the homepage and enter your ZIP code. The current catalog appears in a small box. Clicking on it makes the image large enough to browse.
Turn pages in the virtual circular by clicking on the little arrows on the left (back) and right (forward). The online circular offers zooming functionality for a closer view at a particular item, searching capabilities to find an item quickly and a list of corrections should any apply. You can also print out the circular as a PDF document if you want a hard copy. Past Menards circulars are accessible through the same mechanism, located in smaller boxes underneath the current promotion.
