It is a common practice for some businesses to offer the "Add to Wish List" options for their products or services. It allows their customers to add one product or service to their favorite or wish list and postpone their purchase to another time. This business initiative sometimes is referred to as an open order. The Above Zest Company has such options for its tour services (read "Why Above Zest Is Really Above Zest" and "10 Criteria For Selecting The Best Tour Operator" for details).
When viewing your ideal trip page from the Above Zest website, mobile, or tablet App, there is an open order link for adding that trip to your favorite list. Even if you may not afford the trip now, you can set a projected booked date and let Above Zest remind you prior to your projected booking date. Specifically, Above Zest sends three reminders one week before, a few days before, and on your projected booking date. If not confirmed by your projected date, the open order will be expired. In addition to that, there are a few terms specific to the Above Zest Open Order available on the website.
The bottom line is that the option of the tour open order offered via Above Zest is a safe and easy way to save your preferred trips while postponing your decision to the future. Thus, it is a great resource for frequent travelers, and those who want to make their mind at a later time.
