It turns out that online retailers consider that your choice of web browser tells them something about who you are, and offers you deals accordingly.
Slashdot has this story of different car loan rates pitched to clients based on browser preference.

I was still a bit dubious, but at least one of her previous comments backs up her claims to have worked for a credit card company.
