US buyer tip

Pro-grade mice often drop 30–40% in sales; shape is personal, so check the return window.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.
