Following chunk html code works as expected:
<iframe src="http://www.amazon.com/"></iframe>
But when trying embed inner Amazon pages http://www.amazon.com/gp/product/0672329166/ref=s9_simh_gw_p14_d0_g14_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=1E72BDHD1YZMPYZ2HM4Z&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846 nothing appears.
Firebug shows that request is well executed with a 200 OK code.

Is there some Amazon policy involving this kind of use of their site?
They use x-frame-options to block their content from being loaded in frames.
