HELP!!! Divs getting pushed around in store :(

If you go here: http://www.feeltheneed.net/shop/

You can see the problem. All of my content is getting pushed into the left sidebar??? Is there a reason for this happening. It happens every now and then, sometimes it is completely fine and others it is all out of whack. Is this possibly a bug?

I have no idea why my store is doing this Please help!

Thanks

anyone know what would make this do it? It was fine last night, I haven't changed any of the code.

All that nonsense for a missing closing div tag... should have know. So if anyone ever has this problem I believe that is what caused it because everything has seemed to go back to normal now.
