Bracketing behavior — customers buying multiple sizes to return most of the items — creates a costly cycle for retailers and the planet. Each unnecessary return increases logistics costs, carbon emissions, and packaging waste while damaging margins. Manual monitoring can’t catch this in real time.

Bloomreach’s marketing automation solution automatically detects when customers add multiple sizes of the same product and triggers contextual alerts at checkout. You guide shoppers to sizing resources before purchase, reducing return rates while cutting environmental impact. This proactive approach cuts reverse logistics costs, improves inventory efficiency, and positions your brand as both helpful and sustainably minded.

Checkout Alert

Real-Time Multi-Size Detection Banner

Prebuilt Use Case

Display a helpful banner on your checkout page when customers add multiple sizes of the same product to their cart. The system uses tag-based triggers to monitor cart contents in real time, automatically detecting when product IDs match, but sizes differ.

When bracketing behavior is identified, the banner appears with customized messaging that guides shoppers to your sizing guide without being judgmental or restrictive. For example, show „Buying multiple sizes? Check our sizing guide for the perfect fit!“ on fashion items or „Not sure about your size? Use our Fit Finder tool“ for footwear. The banner integrates seamlessly with your existing sizing resources, helping customers make confident decisions before completing their purchase while also reducing return rates and logistics costs.

Real Results: Isadore's Cart Consolidation Success Story

Isadore, a sustainable cycling apparel brand, used Bloomreach’s cart consolidation weblayer to reduce the environmental impact from returns. When customers added multiple sizes of the same item, a banner offered sizing help and connected them with support. After implementation, 69% of customers removed duplicate items from their cart (vs. 40% before), resulting in a 29% decrease in potential returns and significantly lower shipping emissions and packaging waste.

Target Audience for Multi-Size Purchase Prevention

Fashion and apparel retailers with high return rates from size uncertainty, footwear brands experiencing bracketing behavior, sportswear companies selling fit-critical products, and luxury retailers protecting margins from serial returners. Particularly valuable for ecommerce brands with complex sizing across categories, businesses shipping internationally where returns are costly, and sustainable retailers committed to reducing environmental impact from unnecessary shipments.
