I understand the need to advertise, but...

Hi Shawn,

We use a cookie-based system to limit the number and type of ads that are displayed to our users in each session, so I would recommend configuring your browser to ensure you are accepting cookies from IMDb. For more information on ads and the best ways to prevent repetition, please see:

https://help.imdb.com/article/imdb/general-information/can-you-get-rid-of-the-ads-on-your-site/GDXHL...

If you have tried the above and are still noticing the same ad repeated, please write us back with a description of the specific ad so we can investigate further.

Thanks in advance!

In addition to Steve's reply above, please note that ironically, ad / cookie blocking plug-ins can interfere with the frequency capping itself so if you try disabling any ad blockers, everything should work as expected. 

If this does not fix it, have you selected the option "Do Not Personalize Ads from Amazon for this Internet Browser" on https://www.amazon.com/adprefs ? By selecting this option, Amazon would not apply frequency capping on your requests, and this would explain the behaviour since you are essentially opting out of us storing any information, including whether or not you have already seen the ad.

Well that seems to be the issue, I had just installed System Mechanic Pro, and it cleared and blocked cookies.  All good now...Thank you for the prompt replies!!   Shawn.
