How does one make a return page to their site?

[NST]

No problem linking to where the store is and getting it to come up, but how does one return to their web site if they decide to leave the store without ordering?

I am in the situation, once again, where I need to return to the site from inside the store, and do not see an option for creating this link anywhere?

I don't want to pop-up the store in a new window as I feel many will have to deal with how to handle their default Windows pop-up blocker...

Any suggestions?
