Resize content for "frame" on .aspx page which draws product content from suppliers' page

I have a retail store site, no online sales, which displays the webpage of our supplier in a "frame" in order to have the most accurate and up to date information for our customers. (example)

My issue is that the size of the page it is pulling in doesn't fit in the frame. It looks pretty poor, and part of the content is obscured. Is there a way to scale the content drawn in to the size of the frame?

The same site also has an intermittent issue with the Flash banner loading. When it doesn't load, the layout of the header on the page is a开发者_Python百科wful. Any ideas there will also be appreciated.
