Surveys and Redemptions

i have been doing surveys with the panel station for the past year ,i have redeemed 80000 points, so that's approximately 20x R100.00 vouchers (Takealot, Woolworths and Shoprite)and its been delivered within the 6 weeks period. I might add that my sister also does surveys . Honestly we are still to encounter ANY problems with TPS and the way they do their business, i am grateful for this site
