Amazon taking $5 off anything!

I didn't order anything but can see that it's taking $5 off every order. I have prime so I'm tempted to get some cheap books...

Can we potentially get a $5 product for free?

EDIT Thanks for posting this, compadré.

Yeah, but only if you have amazon prime, since you'd have to put in a $25 order to get free shipping otherwise.
