Can automatic discounts stack with other offers?

I'm running an e-commerce store and want to understand the complexities of discount stacking. I've heard conflicting advice about whether automatic discounts can be combined with other promotional offers, and I'm concerned about potentially losing revenue or creating unintended loopholes in my pricing strategy. I need a clear, comprehensive explanation of how discount stacking works across different platforms and what rules I should establish to maintain profitability while offering attractive promotions to my customers.

The short answer

Track which discount campaigns bring the highest quality customers by comparing 90-day LTV, repeat purchase rate, and refund rate across customers acquired through different discount campaigns. Quality beats quantity when evaluating campaign performance.

In depth

Measuring Customer Quality by Discount Campaign

Not all discount-acquired customers are equal. A 30% off campaign may bring 200 customers who never return, while a 10% welcome offer brings 100 customers who purchase 3 more times. The latter is 3x more valuable despite fewer initial customers.
