I think you may find this interesting. I decided to make a table of the top ten sales department of the major supermarkets in Australia in 2018 and 2017 and then compare it. Sales are in billions of dollars. What I found quite surprising was the way they broke up their departments.
|Frozen foods||3.54||3.32||+ 6.6%|
|Health and beauty products||2.16||2.31||- 6.5%|
|Snack foods||1.77||1.74||+ 1.7%|
It is interesting that the big increases are in the products in the fridge.
I would be interested in hearing how your sales went in those departments.
