Make your call. Which version won, and why? Decide before you open the result. Guessing first is what trains your judgment.

Made your call? See the result

Purchases rose 45%.

What happened

Jared Spool's team swapped Register for Continue and explained that an account was optional. The retailer reported $15M extra in the first month and about $300M in the first year.

Why it worked

People came to buy, not to start a relationship. Registration felt like a cost with no payoff, and many returning shoppers had forgotten old accounts.

The takeaway

Remove forced commitment from the path to value. Ask for the account after the value is delivered.
