Shaded stretches are sales, from our calendar.

Prices we recorded ourselves. Usual is the price on the typical day, with limited-time deals left out unless they ran on most of the days we recorded; Average is the mean of every recorded day, deals included, so a gap between the two columns is a record holding an outlier.

Cheaper in Projectors, and what changes

Things we track on the same shelf for at least 10% less than $849.00, with the attributes the retailers describe differently. Their words, not our judgement — we record prices, we do not test products.

Every change we recorded at Amazon

Every row is a price we saw change. We write one only when a price actually moves, so a gap here means the price held.
