The Chart
| Element | Implementation |

| Free first exchange | No questions asked |
| Extended return window | 60-90 days for exchanges only |

| Sizing audit | Internal review if 3+ customers report wrong size on same product |
| Money-back if 3 exchanges | Last resort full refund + apology |
FAQs
Doesn't this increase returns?
Slight increase in exchanges (good — same revenue retained). But MORE first-time customers convert because of guarantee. Net positive on revenue + lifetime value.
Cost of running this program?
Free exchanges average 1.5x exchange rate of standard return policy. Cost: shipping + handling on extra exchanges. Offset by 10-20% conversion lift on first-time buyers.
