It is right, some other forum scripts have a free subscription option. This was the case in vBulletin, the system I converted from to IPS. But to be fair, the IPS system is way more advanced in all regards. If I compare both systems, IPS saves me more life time because of the inbuilt invoice generation system. In vBulletin I had to create invoices by another program and send it to members needing an invoice. The overall payment rate is higher because the system sends out automatically payment reminder. Bottom line, commerce is a professional tool helping you to get the most bucks out of your members and worth the price.
