Toluna

I joined a new survey site to earn a little extra cash, Toluna. I've received several emails that offer anywhere from $1.00-$5.00 for surveys that take about 10-20 minutes. Sounds good right? The problem is everytime I go to fill out a survey, they already filled their quota for the survey. I signed up with the company about a week ago and just thought that I was getting to the survey's too late. I might get a survey in my inbox and not see it for an hour. But yesterday I was already in my mailbox when a survey came in. I got super excited because it was a $3.00 survey. I clicked on it and can you guess what happened?....that's right...they had already met their quota. I was pissed! I'm going to keep trying with them but I must admit, I'm getting frustrated already. If someone knows the secret to actually getting to complete these surveys, please share.
