Every promotion, yours and your rivals', as it happens
Cannonball shows when a supermarket promotion starts and ends on your products and your rivals', how deep it is, and whether it runs nationally, in one state or in a few stores, across Coles, Woolworths, IGA and ALDI.

The promo calendar draws itself
Every product's chart shades its promotions. Toggle a rival on and its promotions appear on the same timeline, so the cadence of half-price weeks across a category is plain to see.
National, one state, or one store
A promotion that runs everywhere was decided by head office. One that runs in a single state, or a single store, is a different story. Cannonball labels each change with its reach.
Did your promotion actually run?
After a promotion you paid for, check it ran where it was meant to, at the agreed price, and how many stores ran out of stock during it.
