According to the Wall Street Journal (subscription required), Google will introduce a "test" version (or is that beta?) of Gbuy as early as this week, according to those familiar with the situation. The service will undoubtedly compete directly with PayPal and is set to initially attract customers by offering an unspecified rebate to those who use GBuy to complete their online purchases. Also, Google plans to integrate GBuy with its current advertising network, as yet another incentive.
