I have no real experience with ZenCart or checkouts so I told him I would ask around.
Basically, his current check out feels, in his words, "clunky". And since the site has launched, he has had no sales from his 200 visitors over the last two days (although this could be because Google is still struggling to index the site properly). Which puts him far below his 3% conversion rate of his other sites.
What checkout modules would you recommend? Do you have any advice for this situation?
