Look here: http://www.daniweb.com/forums/thread66288.html You can trust them with out credit card info, but I'm not sure if you will be satisfied with traffic bought from them
There's a lot of FAQ web traffic suppliers! Don't waste your time. buy web traffic only from www.easytraffic.biz You absolutely can trust easytraffic.biz with your credit card because you pay them via paypal and the traffic you get is guaranteed!
everything with credit card I think that is OK but it must be different case with there traffic product ,most of the product actually impossible to guarantee because what we talk here is "traffic"the acts of people to "visit our site"there is no guarantee actually about this and you should reconsider the thought all all thought about the means of "buying traffic"
