The fee schedule is not public information but it is believed that there will be a cost associated with using Gbuy. Perhaps it is more important to note that Gbuy will give Google terabytes upon terabytes of information about what users buy. For example, Google will easily direct advertisements of baby products to people who buy baby products. The time saved by consumers will be enormous. Those who do not have babies will very seldom see an advertisement for baby products. Those who buy wine will automatically be exposed to much information about wine.
Investors who do not own Google stock are making a big mistake!
