This is a bare-bones module that simply allows someone to enter their email address to subscribe to a Constant Contact list or lists. The use of their API would be needed to accomplish what you are requesting. That said, you can control what lists your potential subscriber sees from within the Constant Contact account settings.
However, regardless of the options the user chooses, the price of the trip displayed to the user does not change and always displays the baseline price. The new price is only reflected AFTER the use hits "next" and the confirmation page is shown. This is less than ideal because then users have no idea how the selection of these options changes the price of their trip, and many of our users are surprised by the increase in price and frustrated that they had to go through the process before the new price is shown.
I think DT Register can enable the price displayed to change interactively based on user selection by using Silverlight/AJAX, not sure why this is not done because it seems like something that makes a lot of sense and fairly straightforward to implement.
Still, overall a solid product and constantly improviing.
Hello and thanks for the review. I wanted to point out that the 2.7 series of DT Register added a feature where the event price above the form changes dynamically through the registration process as any field selections are made that modify the price. Also, the confirmation page can now display a full breakdown of all included fees and discounts. Thanks!
