I do not know for sure and they are always subject to changes in their policies. You would have to check out the websites you are interested in to find out. Look for their payment policies or their regular policies as that may answer the question. In addition, you can look at their terms and conditions or FAQ’s. If that doesn’t tell you, look for their contact information so you can ask them directly.
A little late getting into this discussion. But my favorite so far is OneOpinion. I think it’s mentioned here. Survey Junkie cool. MyPoints is okay. Ipso, not so much. I did make 300 points today in about 6 hours and every single survey except one I was disqualified for. I was disqualified for the two pointers as well as the higher pointed ones. I’ve never had that problem. Yes you get disqualified, but not everyone out of 30 or so. One of them I actually made to the 98% and was disqualified. I think they didn’t like the fact I was female, except that was answered at the beginning.
You can also earn money by reading special emails, watching videos, or referring other people to Vindale Research. The minimum threshold is higher than InboxDollars; you need to have at least $50 in your account to withdraw funds. This can be frustrating for people who only occasionally do surveys, since they’ll have to wait longer to access their money.
When I first joined and I had issues I thought I’m new at this and will keep at it ti at least get one payout from them. After many surveys telling me that I didn’t qualify after completing the entire survey I got nothing while they got all my answers. This happened quite a bit and the ones that I did get paid for is a few cents for anywhere from 30 to 60 minutes. So it took me like four months to make $68 and wouldn’t you know what as soon as I make a request for my payout I get told I’m not getting anything because my account has been terminated.
