Analysis of sales data for the period 29 August 2014 to 10 April 2015
There appear to be twelve sales groups that repeat about every three months, although the actual period can vary between six weeks and six months. The numbers in this table represent the week each sales group was on sale during the monitoring period, with 29.08.2014 as week 1 through to 10.04.2015 as week 33. Groups are sorted in order of how long it has been since they were on sale. It seems that a group won't go on sale again if it has been on sale in the last five weeks.
