Global Test Market is one of the biggest surveys sites that had been around for a while. This program is totally free to join unlike many scam sites which ask you to pay if someone wants to join their program.Similar This is similar to other survey companies Global Test Market will send survey invitations to your email box.

Generally members from U.S. attend to get more surveys, which on average will take about 15 minutes to complete. At the current exchange rate 1,000 points will earn you fifty US dollars which the minimum cash out level. This company pays out via checks in US dollars. Once you reach the 1000 points you will be able to request your payment. 1000 market points are equal to $50 dollars which it can take up to two months to receive your check.

Personally this is one of my favorites survey sites, we already received our third check.
