A few things to point out here:
1. Store Layouts
There are two different types of change that happen:
- A 'micro review' - i.e. the space allocated to a particular category stays the same but there are changes within that space. For example, lets say a store has 6 bays of space allocated to canned vegetables. The six bays stays remains in the same location in the store but changes tae place to the location of individual items within that space stays the same. This sort of change happens for a variety of reasons - new lines, discontinued lines, seasonality and more space being required for items where space is increasing being some of the main reasons. These sort of reviews happen quite frequently.
- A 'macro review' - this is a change to the space allocated to particular categories. So our six bays of canned veg might become four and move to a different location. These sort of change happens to reflect changing habits and sales. For example, much less canned fruit is sold than when I first started working in retail but much larger volumes of nappies are sold. This needs to be reflected in the space allocated. These sort of moves are very labour intensive and expensive. A few years ago changes to where products that are high in fat, sugar and salt resulted in significant moves and big cost to comply with the new regulations.
Additionally stores will normally have promotional space - typically at the end of gondolas, but sometimes 'in-aisle' because products that are high in fat, sugar and salt cannot be displayed on gondola ends. Bulk displays around the store are also promotional space. Items ion promotion will normally be dual located in the promotional location as well as their normal location. Sales normally increase significantly when an item is on promotion and the additional space is required to help keep up with demand and visually promote the product in what is normally a high footfall area of the store. Suppliers usually pay to have their products displayed in promotional space.
Store normally have dedicated space for seasonal ranges. Examples include Valentines Day, Easter, Summrr Gardening, World Cup (and other events as appropriate) Halloween, Christmas etc.
Store layouts are tightly controlled. Home delivery shoppers are directed to the exact location of items by their picking handset and this technilogy can be used to guide shoppers to the location of items through an app or handset.
2. Electronic Shelf Edge Labels
Most retailers seem to be moving in this direction, they've been around for a few years now. The biggest advantage for retailers is the massive labour saving of implementing price changes.
While you never say never, I doubt we will see dynamic pricing any time soon. Supermarkets care very much about their reputation and I don't think this would enhance their reputation.
3. In-store Bakeries
'Scratch' bakeries are labour intensive and on the way out. For example, Sainsbury's removed the last of theirs in 2025. They are very labour intensive, not just the labour required in store (which has increased massively over the last 10 years - not just the headline rate but all the additional 'on costs' as well). Part bake and bought in quality has improved significantly. Sales of 'standard' bread is in decline with more 'artisan' bread being sold than ever before - this has never been part of the scratch range where I've worked.
