One evening, as you flick without purpose through the internet, you are confronted by a pop-up advertisement:
Bodysuits.com
Thousands of bodysuits
Custom tailored
First 100 customers claim for free!
Normally you would close the link without thought. But this time your gaze and interest is drawn in, mostly by the flashing, neon word 'Free'. You click the ad and are redirected to the site. It seems simple enough. There are a small number of subcategories for suits. You select one.
