Hi Matt,
I think it is a valid use case. From your short description it sounds
like you are adding value to merchants and users, which we love doing.
If your business is all about news aggregation (not deal aggregation)
then it seems like your use of Groupon data is not violating TOS.
You should definitely use the appropriate branding.
If you have a mock up or a prototype implementation of your service
that integrates Groupon deals we'd be more than happy to do a review.
Please send the link and a short summary to
a...@groupon.com.
Kind regards,
Andrei
