Of course. I think the following document is still valid:

> About 100 users order books (they fill the ISBN the title and the

There are a few shop extensions around, namely tt_products, kb_shop or 
tx_commerce. You can find out about these and any other available 
extensions at http://typo3.org/extensions/

The best way is to convert them into a proper extension. However, smaller 
scripts can be included as a USER/USER_INT object via TypoScript:

In my opinion, porting an existing application to a TYPO3 extension is 
the best way of learning how to implement extensions, so go ahead do 
that. Including existing scripts as USR-objects often is the lazy way, 
you won't learn much from that.
