I am not sure how this can work even from IT pont of view.

Cleaned PC (cleared cookies, temp files, logs, saved info. cache - everything)

Opened up IE in one window and Chrome in another.

At marriott website, searched for properties in the same city for the same date.

Rates shown were different in Chrome vs IE (in most cases chrome was cheaper by 20% but for the two of the properties it was expensive by about 8-9%)

Never seen this on any website in any industry. (in my experience, that is)

Called up a friend in a different city (totally different ISP and of course different IP addresses), he was able to duplicate the scenario on the third attempt (on the first two attempts he got same prices on both browers)

Has anyone else ever notice this?
