This one mighta even caught lil 'ol paranoid/perceptive me. I never trust anyone for anything these days, but the crooks always try to stay one step ahead of the crowd. I buy on Amazon sometimes. There's what-to-do-if stuff here, but I'd say just let it all ride, the real Amazon people will send an 'Item has been shipped' email when it's shipped.
I'd say never enter your personal info anywhere except when you yourself directly open and login to an official website. So don't enter info on a re-direct. If you're uncertain, go to the real website and check your order status there.
We think we got it all figured out, but could slip up.
Hope this helps someone out there.
