We send out upgrade CDs to all customers on annual support on a regular basis not less than once per year. Upgrades incorporate new features garnered through feedback from our customers. They are also necessary to incorporate changes to remain compliant with new operating systems and new bar code handhelds. An unscheduled upgrade CD may also be sent to a customer to resolve a problem that the customer has identified. UPS domestic ground shipment costs are included as part of our support. Priority shipping and international shipping costs are not included.
