I currently do surveys for Ipsos Access panels, where you can get vouchers such as boots or argos for compensation.
I have been happy with their services, and they always pay out as promised.
I wanted to join more survey sites that offer this, but most you get paid in points that are converted into cash or online offers for your points. Either that or they are a scam!
Does anyone know any free to join survey sites that send you vouchers for compensation or similar?
