Per several others, I agree:
1. Buyer is an a$$hole of the lowest order.
2. Buyer deserves nothing more than the best reproduction of the manual you can provide. Many, many products do not ship w hard copy manual these days.
3. If buyer funded pp via a credit card, you may be in a tight spot.
4. Your "error" was harmless/negligible.
5. Your offer to provide a manual negates the error.
6. When you purchase via mail order few sellers provide refund for shipping in either direction.
7. I agree w others that your most pragmatic solution may be to offer a refund, less shipping, to be credited to "buyer" after receipt in same condition, shipped at "buyer's" expense and risk.
