You could either:
- bring your smartphone and have that page saved, by flipping to the next page, it shows the dates of the flyer
- what I do ~ print screen that page, but first hover your mouse over the little clock on the bottom of your screen. Today's date should pop up, then I hit Alt + PrtScrn, paste to your Word program, and print. This way it shows that you found it online today, not 2 months ago. Works at my WM :)
- print the front page of the flyer, then also the page you need, staple together.
