Why is there no "money back guarantee" offered with the Plus package?

The nature of some of the services offered in the Plus package means that third-party licenses, payments to trainers and other partners may be made by ProZ.com at the time of your membership purchase, and those will not necessarily be refundable to ProZ.com. Instead of a pro-rated refund on your Plus package, you will be offered the option to switch to the Standard package. However, if you are in any way unsatisfied with your Plus package experience, please contact a member of the site team, we want to hear from you.
