$279.00 is its usual price.

The middle price across the 10 days we have watched it, counting the days a limited-time deal was running, was $279.00. Today's price is also the lowest we have recorded, so our record has nothing lower to wait for — but a price this close to the usual one is not a discount, whatever former price is printed beside it.

The lowest since we started tracking it on October 1.

This describes the prices we recorded. It is not a forecast of where this one goes next.

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.
