Amazon Prime Day countdown begins. The sale starts 12 July with early laptop deals up to 58% off on HP, Dell, Lenovo, Asus, and more top brands live now.

Amazon expanded its annual Prime Day sales event this year to four days from two. But now that the event is up and running — it started Tuesday and runs through Friday — there may be signs it’s losing some of its bargain-hunting appeal among consumers.

Though Amazon Prime Day doesn't officially kick off until July 8, you can shop big savings already on brands like Apple, Dyson, Shark and more.
