The trial version allows unlimited downloads of hotel price data from two (2) hotels on five (5) dates. As we have put in our terms and conditions, the trial version of our software serves as a 'proof of concept' sufficient enough to help you make a decision as to whether you would like to purchase the 39 USD$ full commercial version.
Not a problem to customize the paid version (remove our logo and place your own). Feel free to upload a copy of your logo to the forum (or email to it following payment).
