Competitive price tracking
Know the day a rival changes price, starts a deal or adds a size.
Shelfprice records every price on Kroger's shelf at each price check, regular and deal prices apart.
Words used here (tap)
- Rival:
- Another maker's brand sold on the same shelf.
- Regular price:
- The price without any deal. A deal is a promotion price below it.
- Price per ounce:
- A pack's price divided by its size, so small and big packs compare fairly.
- Price check:
- One pull of Kroger's prices from the store on one day.
- Product type:
- The kind of product within a category, such as Regular, Greek or Kefir yogurt. "Regular" here is a kind of yogurt, not a price.
- Pack:
- One size of a product, such as the 32oz tub. Flavors of one brand and size are one pack.
Every rival's price, tracked.
Change detection
A deeper deal, a price rise, a shrunk size: caught in the next price check.
The answer, not just the data
Every opportunity names the move to make and why, in words.
What gets tracked
Dated price history
Every product, dated, so you know exactly when a price moved.
Deals and regular prices, kept separate
A temporary deal never distorts a rival's regular price.
Trend, not just today's shelf
A rival's price per ounce over time, so a one-week deal is not read as a price change.
What this looks like on real data
Above, the changes between the last two price checks. Below, one real finding from Kroger yogurt.
A brand that is only near the typical price while on deal.
Product type: Regular
GoGo Squeez's regular price is 20% above the Regular median, any size; deals bring it to 7% above
Without deals, GoGo Squeez costs 20% more per oz than the median pack in Regular (the median across all sizes, not the same-size comparison Price tiers makes). With deals, 7% above the median.
Price per ounce against the typical (median) price in the segment: regular price 20% above, on deal 7% above.
- What to do
- Decide whether the regular price holds without deals, or should come down toward the median.
- Why it matters
- When deals end, GoGo Squeez is 20% above the median again and the extra volume may go.
