You need to be smart, I was rejected for a lot of surveys, now I just wait till I get invited through email. I only do surveys when I have earned a 25c token as well, most of the time just once/twice a day. I earned my 30 dollars in about 10 days, I listen to music all day, and I am multitasking surveys/watch videos/doing my household tasks. It adds up quickly this way. I will let you know what happens when I apply for my first check. You better can find a job if you need to provide for a family however if you need some pocket money it is a nice way to generate some little extra.
I got my check after I submitted the request.
Things I discovered and learned from: When you sign up for an offer, write down you did that. Sometimes it will take 2 or 3 weeks to be rewarded and Inboxdollars seems to "forget" to credit you for the signups you did. You'll need to actively contact them to get the credit.
