Also, with the Greenfield daily surveys...if you get the screen saying "Sorry you didn't quailify today..etc etc." that doesn't mean you are done for the day. You can keep trying (using all your same info and email).
I think alot of new people don't realize that. They see the sorry screen and quit for the day, but Greenfield is constantly loading new surveys, so if you have time to check back later in the day you may be able to get one.
Also, if none of the options fit you (ie "Do you have kids age 1-4?). If you select "None of the above" you still may get surveys that way. I'd say about 80% of the time there's been one for me for None of the above.
If you are going for the daily survey and the extra your2cents survey, they are both offered through Greenfield...so you have to clear your cookies b/t taking them, or only one will register/credit (usually).
It is totally do-able to make supermember with little shopping. Of the $1,298 I've earned, only $88 of that was from shopping. It just depends how much time you have available to put in. I work at home, so it is easy for me to check back throughout the day for surveys.
Also, as pp stated, the daily surveys on the weekend credit on Monday, during the week they credit the next day, sometime after 12:30pm. The your2cents and otx credit usually within an hour.
Also...the surveys usually have timers. If it seems you are going to fast you will be booted out with a sorry you didn't qualify. Take your time and read everything as if you were reading the first time, especially the first screen with the type of paragraph that asks you to read thoroughly and do you agree to be honest type question. If you just speed through that greenfield will assume you aren't serious about giving honest answers and boot you out from the get-go.
