I am looking for a cached copy of a website (www.shopthepackersgear.com).

They have recently changed their website, and I would like to find a copy of their old one. When I use Google Cache it skips by the page then goes to google.com.

I only need the version from maybe 2 or 3 weeks back. Is there some way to find this or did the people who own the site delete all evidence? I'm not sure what is possible these days and I need help.
