Many offers will have a page full of optional free offers and you have to choose "yes" or "no" for each one. You may have tried to choose "no" to all of the offers, but a box pops up that says, "You must choose YES to at least one offer."
Don't be put off by this. Choose yes to an optional offer and click submit. On the next page, you will see a form to fill out for that offer with a Yes or No option at the top. If you don't want to fill out the optional offer, click No and it will go to the next page. You will still receive credit for completing the main offer if you follow this route.
