We're just a few days out from Prime Big Deal Days on October 6, and Amazon is already offering some savings on accessories including Anker chargers, Samsung monitors, and 4K TVs. We're also tracking deals on the new Mac mini, Mac Studio, and Apple Watch Ultra 4 this week. Note: MacRumors is an affiliate partner with some of these vendors. When you click a link and make a purchase, we may receive a small payment, which helps us keep the site running.
