In general, surveys are a great way to earn credits. In the past few months, I've earned enough credits to buy new high quality driver, 3 wood, hybrid, irons and putter. Some of the surveys are worthless. The surveys that offer 75 credits generally offer me about ten surveys for which I don't qualify because of my age and because i'm retired. Sometimes, after about fifteen or twenty minutes of rejection, I am awarded 5 credits. Usually I get nothing. Last night, I was entered into a survey that took about half an hour to complete. At the end, I was thanked for my input and then I was offered another survey. I received no credits Even though I'm retired, my time is worth something. I recognized the survey site that I had been working with and, had I taken that survey by going directly to the site instead of through WGT, I would have earned a dollar toward my next $100 amazon.com gift card.
