My b2evolution Version: 1.10.x

I just set-up my b2evolution acount this morning....
If I go to Zazzle, or Amazon, and I generate one of their links on the website - is there no way to post it into the b2evolution blog?

I set a new website to basically help promote my original designs on zazzle ... and zazzle creates the link for me.
If I have to use the b2evolution interface this will take me forever..

I did hit "advanced" ... and I tried the xhtml button...
but nothing is working.
I got error messages when I hit "preview".

Is there a way to post straight html code on to my blog ?

Thank you for your help with this.
