Surveys on iTunes resulting in Donuts
I don't know about iTunes, but I have an app on my phone called "Google opinion rewards" that gives me little surveys and adds small sums to my Google Play balance. So far it's only been about $4, but...

I do the Google Opinion Rewards too. My first survey gave me $1, but the last two I've gotten gave me .20 or so each. I only get one every 2-3 weeks, too. Wish it was more often, but meh, at least it's free.
