Some people suggested _SESSION which is pretty handy for little bits of data but I'd checkout ctools' object_cache. Or better yet, since you're creating a form that keeps state, maybe ctools' wizard form generator is what you're looking for. It can do some pretty handy stuff and is well tailored for use with ctools' object_cache. Your shopping cart use-case sounds like $_SESSION or a dedicated table keyed by session ID and uid to me. Also not sure why you want to reinvent the wheel -- doesn't Ubercart or eCommerce or anything else in contrib contain a ready Cart module already?

He did say "like a shopping cart" so I assume it was only an example. Using a prebuilt and tested module is always a big win though. -- James Gilliland
