Business Question
The team was looking to understand whether gifts with purchase were effective in building a strong, loyal customer base.
They were looking to answer the question: Should general discounts on the first purchase be considered to replace the gift with purchase offer?
The Solution

- Gift with Purchase Impact on LTV
Utilizing Decile, they discovered that customers who were acquired with a gift with purchase had an LTV which was 78% higher than customers who were acquired without it.
- Type of Gift with Purchase Analysis
The type of gift with purchase (product/product category) did not have significant impact on overall LTV.
The Results
67% Higher Repurchase Rate
compared to customers who didn't use a gift with purchase, when looking at a six month post-acquisition window.
DECREASE IN MINIATURE PRODUCTS COSTS
The business stopped changing the gift with purchase on a monthly basis, instead focusing on one gift per purchase per season.
Reduced Ad Spend
Monthly advertising spend was reduced as a result of improved targeting.
