Online retailer Amazon is giving a 1.57 percent discount to registrated users of its recently launches A9 Search Engine. This is aimed to boost A9 use and promote buying on Amazon.
In a note on its Web site, Amazon said that revenue from Web search advertising on A9 will help offset the cost of the discount, which equates to pi divided by two -- Amazon's way of "sharing the pi."
A9 debuted earlier this week and is the project of Amazon's Palo Alto, California-based Internet search unit of the same name. After the roll-out of A9, many analysts and industry watchers had wondered how Amazon would use the service to spur sales on its site.
The discount program began Thursday afternoon.
Amazon shares were up 31 cents, or 0.73 percent, at $42.88 in afternoon Nasdaq trade.
