How to read a Black Friday sale

• Green is a real drop. Today's price is under the usual price: the highest price on at least 7 of the last 30 days.
• Amber is the store's own sale. The store shows a crossed-out "was" price. It may be a real cut, or a price it rarely charged; we don't count it.
• A price raised just before the sale doesn't make a drop. A usual price needs at least 7 days at that price in the last 30, so a few days of a higher price don't count.
