I was hoping to find anyone who has tried http://www.clickcartpro.com/

It looks pretty good and I like the addons that are available like the froogle feed and a bunch of others. It is kind of pricey but this is for a client and he really wants the froogle feed automation because he has over 2000 products and about 10% of the products will change on a regular basis.

I have looked at Oscommerce, x-cart, zen so I am looking for posts from current or previous users of this software.

Thanks. :)

Unfortunately nope. My advice is to use only proven resources. But it's shurely your choice, your client's i mean.

froogle feed is become common feature in shopping list, if you familiar with PHP, i recommend oscommerce.

if you want good support, then choose X-cart, the v4.0.14 was just out recently.
