This is what I'm thinking. Take a small (for Amazon) that will be dwarfed by people who sign up for or renew Prime memberships hoping to luck out on a similar deal in the future.

according to random people in the slickdeals thread the loss was $16 million

Companies pay a whopping $5 million to run a 30-second ad during the Super Bowl....

This super sale (if everyone gets what they ordered) will have much deeper impact than a 30 second commercial.

Believe next year, millions more people wil be looking for deals on amazon on prime day....

Well executed "price mistake" ;)

So 0.1% of profit. Is that not small?
