Many shopping carts track persistent data (including running totals) via
cookies. If you just want to know *how* to do what they do, the short
answer is "cookies" <http://php.net/sessions> <http://php.net/set-cookie>.
But I doubt any of them are doing so with the *intent* to prevent onscreen
data from being viewable in the source.
