Thanks for your feedback!
We certainly don't mean to offend with our advertisements. We think renting celebrities to promote our "Save the Money" campaign is pretty funny, but we understand if it doesn't tickle you the right way.
In fact, we're already raising awareness and funds for organizations who are doing work around these causes. Please go to http://savethemoney.org and you will have the opportunity to donate to any of these causes. Groupon will gladly match your donation.
Additionally, we do occasionally feature other real charities on our site, so if you have any suggestions for us, please let us know here: http://groupon.sponsorships.
Thanks again for your feedback! Let me know if you have any other suggestions or questions.
