    Yup. Thats the type of chart I would call a rolling sales chart. Amazon does the same, as does Bestbuy.

    Many retailers do frankly.

    Waiting a week can often save you 25-30%, and the high price would have been labelled a sale just the same as the low price, so no one would be any wiser to this without tracking the price.
