Stop using iFram

I currently display our blog through an iFrame at http://eplantsource.com/Home/blog/ and I don’t like this solution because I can’t link directly to any of my posts and still be within our website. I can only link to the main blog page. It also slows down views of the site.

The reason we are doing it this way is because we have a highly programmed site for e-commerce and the header navigation has a lot of programming to get our customers to the right spot, we can’t simply replicate the header and reproduce it in WordPress.

Is there a way to embed the blogs within our site without completely recreating a WordPress site that just looks like you are in our site?

Thanks for the help!
