There seems to be 4 ways to get surveys.

1. Email from E-rewrads. I just got one after nothing for 2 weeks. I think they don't like to send out lots of emails as there is a cost per email.
2. On the home page (I rarely see these)
3. Click on an old email link that was already used. This search for a new one - sometimes. Interestingly, these surveys don't appear on the home page.
4. Through the App - which has surveys that don't appear in email or on the home page for me.

Hard to know why E-rewards does it like this. I wonder if it is to keep costs down and get a wider spectrum of respondents (compared to the same 1,000 people always doing all the surveys they would be potentially eligible for)
