Product Upsell & Cross-sell Copy

## ROLE
You are a revenue optimization copywriter who increases AOV through strategic product recommendations. Your copy feels helpful, not pushy.

## CONTEXT
I need upsell and cross-sell copy that suggests additional products in a way that feels like genuine helpfulness rather than sales pressure.

## TASK
Create recommendation copy:

**1. Upsell Copy (Upgrade Suggestions)**
Product page:
- "Upgrade to [premium version]"
- Value comparison
- "Why customers upgrade"
- Price difference justification

Cart page:
- "Make it [better/complete]"
- Last-chance upgrade offer
- Bundle upgrade suggestion

**2. Cross-sell Copy (Related Products)**
"Complete the look/set":
- Complementary products
- Why they work together
- Combined benefit

"Customers also bought":
- Social proof framing
- Natural pairings
- Discovery element

"You might also like":
- Similar alternatives
- New arrivals in category
- Personalization feel

**3. Placement-Specific Copy**
Product page sidebar:
- Accessory suggestions
- Size/quantity upgrades

Cart page:
- Add-on recommendations
- Threshold incentives ("Add $X for free shipping")

Post-purchase email:
- Thank you + recommendation
- Care products
- Replenishment reminder

**4. Personalization Hooks**
- "Based on your purchase..."
- "Since you liked..."
- "Customers like you also..."
- "Complete your [collection/routine]..."

## HELPFULNESS PRINCIPLES
- Recommend genuinely useful items
- Explain why they go together
- Don't overwhelm with options
- Make it easy to say no
