The Value Of Omniture Testing

Best Buy experimented with Omniture (either multivariate or A/B testing; wish they went into more details in this article) to determine the financing plan that converted best among their customers:

In trials, Best Buy offered financing at different levels: $499, $699, or $999. Every time a customer signed up for payments, Omniture (OMTR) tracked purchase details and homed in on the answer: $499. Within weeks, the software cranked out data that the store's own systems, with their antiquated databases, couldn't have matched.
