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.
Second, there is nobody that’s making $3500 a month filling out online surveys. Sure, there are people who may earn $1000 or even $2000 a month, but they are in the minority. For most of us, it would be impossible unless you join every survey site that there is and spend every single waking hours filling out surveys. And that’s assuming if you are lucky enough to have that many surveys available, to begin with.
Gold members are given the option to either select the cards without creating an account or create an account for additional benefits. Account holders with a Tango card can cash out for significantly higher merchant amounts and they can also choose to send their earnings via email to family and friends as gifts/ donations. There is no additional fee for eCards. Prepaid Visa cash cards are processed by Swift.
IPoll provides surveys via their site and mobile applications, and this has made it easy for most iPoll members. In case you are waiting for someone in a parking lot or you are in a waiting line in a bank, or when getting groceries, you can utilize this time to complete some surveys using your mobile phone and make money. iPoll offers its subscribers $5 upon signing up. Once you join, you can take surveys and get paid via PayPal.
I don’t see PaidViewpoint on your list. I like using that site. I signed up for it on June 28, 2016, but I guess I forgot about the site and stopped using it on July 24, 2016 but had a total of $1.91. I started using it again on May 5, 2018, and I’m now up to $27.05 and have a trait score of 10, which is the highest. The surveys are easy and you don’t get disqualified. I mostly earn 10 cents, but once in awhile I earn some good money like 62 cents. It does take awhile to add up, but it’s free money.
When brands want to find out what consumers think about their product and services, they turn to market research companies. Market research companies are the ones actually administering the surveys on behalf of the corporations looking for data/feedback. Think of online surveys as a type of focus group, except in this case, everything is done online.
