Is that your page or are you bringing that page in by way of an iframe or what?
It usually helps to give more information about the elements on the page.
If you have access to the code for that page, then just "hide" the price div.
If you learn more HTML and CSS and also learn how to use your developer's tools, you too can find out where the code is. I notice that the CSS is minimized (most of it seems to be on line 1). Good luck finding that rule.
