Had a unicorn moment a while back. Ordered an SSD and for whatever reason the seller didn’t use detailed tracking but only the basic “has been delivered” one. Amazon status turns from “Expected today” to “running late”, thing is: the package was there (letter sized, hence no accurate tracking info… on a 100€ package) tracking status did NOT update so I just got the money refunded, while still getting the ssd. I was tempted to try my luck again but ultimately decided not to.
