Are they (Gooogle and WikiBuy) selling your purchase history to anyone?
A friend of ours recommended something called e-bates, that they use on Chrome. We studied up on it....and they (the ebates plug in) track your web activities AND sells the info :(
The fact is ANYONE who sells online is tracking every move they can about you in order to market to you. EBates, Google, Amazon, Walmart.Com, it doesn’t matter. Some may have more information than others but they all do it.
