Here is proof of payment from SwagBucks.
SwagBucks is a search engine powered by Google and Ask. Each time you use their search engine you have a chance at winning "SwagBucks" which can be redeemed for prizes such as gift cards, t-shirts, downloads of songs or tv shows, paypal cash etc.
It cost me 70 swagbucks to receive 5 dollars in my paypal account. I was able to earn this in about a month just from doing my regular daily searches. It did take about 2 weeks for me to receive my payment..I have heard of others getting items much quicker..so it's possible paypal payments take a bit longer..The important thing is that they DO pay.
Remember you can increase the amount of swagbucks you earn by referring your friends. You will earn up to 100 SwagBucks for every single person you refer.
