Hi John,
Depending on your purchase date, you may qualify for a free upgrade. Please send an email to support@smith-consulting.com with your User ID and purchase receipt so we can work with you on this.
Every release of the cart has at least a couple bug fixes which is the nature of business for any software company. The cart comes with 3 months of free upgrades from the date of purchase which is inline with other module vendors and gives you alot of time to determine if a key item like shipping is not working in the version you have installed and requested/obtained a hotfix and/or new version for the function that is not working for you . We ask that customers maintain an active cart maintenance plan so you will have access to cart downloads area throughout the year as needed. We release new versions of the cart frequently with bug fixes, security patches and new features which provides a level of protection for your ecommerce site.
We appreciate your business very much.
Thanks,
