Home improvement and DIY pricing data
Data Purl tracks home improvement weekly across the major home improvement chains and online retailers: tools, hardware, building materials, paint, outdoor and garden. It shows price moves on identical products, promotional intensity around seasonal events, and each brand's presence across retailers.
What is tracked
- Price changes on identical products, including imported categories exposed to tariffs
- Promotional events and depth by category and retailer
- Brand and private label assortment by retailer
- Availability through seasonal peaks
Questions it answers
- Are tariffs being passed through to shelf prices on imported tools and hardware?
- How promotional are the big home improvement retailers versus last year?
- Which tool brands are gaining or losing assortment at each retailer?
Key metrics
- Matched-SKU inflation: The price change of identical products observed in both periods, which isolates true price moves from changes in product mix.
- Markdown breadth: The share of a brand's or retailer's live products that are selling below their full price at a point in time.
- Share of shelf (online): A brand's share of the products a retailer lists in a category, measured on the retailer's website.
- Price gap: The percentage difference between the price of one product or brand and a comparable alternative, such as branded versus private label.
