I belong to almost all of the sites you listed and out of all the surveys I take I don’t qualify for 95% of them. I will spend 15 minutes with generic questions with them collecting information about me then when done they say I’m not eligible for the survey or they have reached the required amount of people for that research. I can understand the reaching the required amount of people but I would think I would qualify for at least 1 or 2. It’s really discouraging when you take all that time to do the survey and not even get any points for doing so!
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.
In my opinion, Inbox Dollars is a scam. After registering and wasting hours upon hours to make a few cents I started receiving a swarm of emails, 83 in one day to be exact, from the companies I was questioned about in the surveys. Not to mention an abundance of calls from unknown numbers. What an invasion of privacy! This is not worth the hassle. Be smart and don’t fall for this one!
In a few cases, InboxDollars directed me to “exclusive offers” instead of straightforward surveys. One required me to give my name, address, phone number and birthdate to earn money and enter a sweepstakes for a Target gift card. Another time, I was prompted to give my email address and choose between Coke and Pepsi in exchange for $1 and a sweepstakes entry. I didn’t want to give my contact information to what appeared to be third-party sites, so I clicked out of these promotions.
