Integrating Other Site

On test3.admaticonsulting.com/, the link ‘Shop’ links to my client’s company store, nspwellnesscenter.mynsp.com/. Currently, it just sends them there, without warning.

I imagine a better way, with either creates a pop-up window, or embedding the body of the page so we can keep the same header.

I don’t the best way to handle this, but I imagine there is a better way than what I am currently doing.

Any ideas?
