In the competitive world of children's footwear reselling, CSSBUY agents have developed an innovative solution combining growth tracking and purchase prediction. By leveraging the CSSBUY spreadsheet function and understanding pediatric foot development patterns, resellers can dramatically improve customer retention for Nike kid shoes purchases.
The CSSBUY Growth Prediction Model
The system works by recording two critical data points during the initial purchase:
- Current shoe size (European/US sizing standards)
- The child's exact age in months
Using pediatric research showing most children's feet grow approximately 0.5 sizes per quarter, the spreadsheet automatically generates a "size-up timeline."
Sample Growth Prediction
| Age | Current Size | Projected Size | Alert Timing |
|---|---|---|---|
| 48 mo | 25EU | 25EU | Initial Purchase |
| 51 mo | 25.5EU | - | Pre-alert |
| 54 mo | 26EU | - | Purchase Push |
How the Repurchase System Works
- Initial Purchase Logging: Agents record the child's metrics during first sneaker purchase
- Spreadsheet Calculation: CSSBUY templates automatically project growth intervals
- Smart Notifications: The app triggers alerts 2 weeks before projected sizing events
- Value-Added Content: Clients receive educational videos along with product suggestions
This method proves superior to standard reminder campaigns by timing suggestions with actual physiological needsCSSBUY research data, precision marketing increases repurchase conversion by 38-55% compared to conventional methods.
Real-World Success Example

- Average customer lifecycle extended from 1.2 to 3.7 purchases
- 67% open rate on growth-alert messages (vs 24% for promotional emails)
- 35% attachment rate on matching sport socks with size-up notifications
"The spreadsheet predictions became so accurate that parents would message us before
