A business-to-business software vendor experiments with two offers – free shipping vs. a discount worth substantially more than the cost of shipping. The emails have identical copy, identical images, and nearly identical subject lines – differing by only one word.

Try this: Pick 10 or more tests and make your best educated guess at choosing the winner.
