you gotta love those recommender systems that websites have, like "if you like this movie, you'll probably like these others... " or "customers who bought that item also purchased the following.." but i just saw the best one on amazon, promoting their new apparel section:

Customers who wear clothes also shop for:
Clean Underwear from Amazon's Target Store
Ladybug Rain Boots from Amazon's Nordstrom Store
Arm Warmers from Amazon's Urban Outfitters Store
Cheetah Print Slippers from Amazon's Old Navy Store
For a limited time get $30 to spend at Amazon when you spend $50 in Amazon's new Apparel Store!

i dunno.. i just thought it was very funn :P
