Required only if you are offering a trial period.

OR if your Initial Price is different from Recurring price.

If you have no trial, or if Initial price and Recurring price are the same, then leave this empty or set it to 0.00

Example Settings

Your monthly recurring is $97, With No Trial
Set this field "Trial Price" to blank or 0.00
Set "Recurring Price" field to 97.00

Your monthly recurring is $97, With a $1 Trial
Set this field "Trial Price" to 1.00
Set "Recurring Price" field to 97.00

You wish to offer a FREE trial, followed by monthly payments of $97
Set this field "Trial Price" to 0.01
Set "Recurring Price" field to 97.00

The reason for setting trial price to 0.01 for a free trial, is that DAP does not allow for fully free trials. You must charge at least 1 penny, because if you do 0.00, then in the case of merchant accounts, the credit card of the buyer is never validated, so come recurring time, the card may fail to be charged.
