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.
In addition to the free offers, there are “paid” offers, too. i.e. Buy a bouquet of flowers through an online florist, get $7.00 back in your InboxDollars account. Lots of similar cash back offers for subscription box services and eCommerce sites. If it’s something you were already interested in, it’s not bad. Otherwise, no point in spending (read: losing) money in order to make money.
Like many other reviews, I used the site properly but as I reached the minimum $30 payout threshold, they terminated my account with generic multiple choice possible reasons of using VPN / acting like a automated BOT / having multiple accounts - none of which was true, perhaps I accessed the account once or twice with VPN still enabled, but that didn't prevent them from earning their partner referral fees they partially share with me while I wasn't using VPN. They can block access to site while using VPN so they ensure proper tracking as you complete each offer. I earned offers while not on VPN, so accidental VPN access that doesn't impact any specific offer they earned through me becomes their dishonest way of stealing the bonus money from you. Support says they escalated to 2nd level support that will respond with an email in a few days, of course they don't.
InboxDollars will occasionally post a tweet, post to their Facebook page, or hang a picture up on Instagram that contains a special redeemable code. You then have until 11:59 CST to redeem that code on the right sidebar of their homepage. It’s entirely free to participate but you can basically only win if you follow them on those social media accounts and happen to notice when they post a WinIt code.
I have been using Inbox Dollars for months now. I am at $32.60 as of right now. My amount has been the same for weeks. I click on the paid emails, and I am not being credited. I wrote to them and all I got back was that I did not have enough funds to cash out. I very clearly told them that my amount is frozen and that I am not being credited for the paid emails I click on. So I try to contact them once more to explain my problem again, I got no response. So I wasted months of my time for absolutely nothing. This site stinks! It is very time consuming. Alot of the surveys you do not qualify for. You sometimes are filling out surveys for several minutes until they decide to tell you that you do not qualify for the survey. I am upset that I wasted so much time for absolutely nothing in return. This site is a complete waste!
The survey panel will invite you to participate in surveys via email. When you get an invite, you’ll answer some questions to determine if you qualify to complete the survey. If you do not qualify, My Soap Box still awards you with 10 points. However, if you qualify and complete a survey, you’ll earn between 750 points to 1500 points, which is $0.75 to $1.50.
How it works: LifePoints is the survey platform of a company called Lightspeed, which is owned by Kantar (one of the world’s largest market research and consumer data analytics firms). The platform was formed as a merger of two of the company’s other products, MySurvey and Global Test Market, and gives users a variety of ways to earn points that can be redeemed for cash:
