Inspiration – Test whether inline quantity break toggles lift units per order and AOV

Overview

Goal: Increase AOV by showing simple quantity‑break savings near the quantity selector.

Build time: 5–7 minutes.

Expected impact: 6–15% uplift in units per order and 4–12% increase in AOV.

Hypothesis

Shoppers often miss tiered savings hidden in tables or banners. A clear, inline toggle (e.g., “Buy 2 save 5% / Buy 3 save 10%”) next to the quantity selector makes the value obvious at the decision point, nudging customers to add more units without feeling pressured.

Assumptions

• Visibility Drives Action: Savings shown at the quantity control outperform distant promo copy.
• Choice Architecture: Predefined tiers reduce mental math and speed decisions.
• Trust & Clarity: Transparent per‑unit pricing and total updates maintain confidence.
• Category Fit: Works best for replenishable/consumable items or multi‑user SaaS seats.

Setting up the experiment in Personizely (Content Test)

Run a content A/B test with:

• Control: Standard quantity selector with no tiered savings UI.
• Variant: Inline toggle/chips showing “Buy 1 / Buy 2 save 5% / Buy 3 save 10%” that updates price totals.

Keep tiers simple (max 2–3), display per‑unit and total, and ensure changes reflect in the cart.

Recommended configuration:

• Placement: Product page, directly adjacent to the quantity selector and Add to Cart.
• Targeting: High‑margin or replenishable SKUs; returning users; carts within 60–95% of free‑shipping threshold.
• Traffic split: 50/50.
• Goals: Primary = AOV; Secondary = Units per order, Add‑to‑Cart rate, Checkout start.
• Trigger: Immediate.

Additional notes:

• Be truthful about savings; base discounts on MSRP or current price consistently.
• If inventory is low, cap tiers dynamically or hide higher tiers to avoid OOS frustration.
• Avoid stacking with other promotions during the test to isolate impact.
• On mobile, use horizontal chips; ensure tap targets are large and readable.

This Content Test will show whether surfacing simple, inline quantity breaks at the point of selection increases units per order and overall AOV.
