Interspire has the most feature filled shopping cart system at the time. It also had a wide suite of offerings like the email marketer tool which was leaps and bounds ahead of its time

I am a developer and I used Interspire for 2-3 years. It is developed with very strong and advanced programming principles. I liked everything I saw in Interspire from coding to front view for admin and customers as well.

I like nothing about it. it never worked.
