I have been trying for a few weeks to find a Joomla! shopping cart that is easy to use, has good documentation, is affordable, and with fantastic ratings.

No luck.  So I think I will just use PayPal buttons and cart for now. I don't have so much inventory that I can't keep up with it. A lot of my items are one of a kind.  

Well, that was some wasted time.  I will look again if business grows and I move to Joomla! 4
