If you have a promotion or offer on then advertise this immediately as your home page or eCommerce page loads. Point your visitors to where you want and add a button to make it even easier to direct them to the relevant page.(note this is different to Popups discussed in another Inspirational article as these are automatic popups and not via a button).
The pop boxes can also be set up to load upon specific instances such as number of times a visitor hits a specific page.
