[ic] Can't add second item to cart bug in online demo

[Peter]

I just discovered this in the online demo and have not had the time to
track it down, but it's a pretty major bug, imo.

1.  Click on an item in the home page (Tested with os28007 displosable
brush set).
2.  Click to add it to your cart, item shows up in the basket page as it
should.
3.  Click on another item in the home page (0s28004 Ergo Roller)
4.  Click to add it to your cart

You get the basket page with just the first item showing and red error
text of:

"* expired: That link was expired. Please try ordering again."
