When you first check Points2Shop you may think that points2shop is SCAM and is not a legitimate website but it's not, they have been around for one year longer than most of the gpt sites and they do send prizes to all members. You can check points2shop forums and see many members have received their free prizes from points2shop and posted their proof. Beside proof prizes, you will find proof of payment for referral earning (you get 1$ for each referral)
