The site that this was deployed on took some time--osCommerce was evaluated and discarded, and $130 was spent on a buggy DigiStore and mambot which proved completely worthless for tangible goods selling. With time running out, this option was installed--and covers all the bases!
OOTB setup will take a little time--some items are not intuitive or things that most will not want are turned on by default like the rating feature. Version 1.1.13a corrects some of the complaints made earlier--but also makes certain 3rd party modules or mambots obsolete. But we all know that it is just a matter of time before that catches up.
Want great eCommerce that is well integrated with Joomla? This is it, and tremendous thanks to the developers.
