There might be a better method. 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.

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.
