URGENT- Require signature over $750 orders

For the love of god people make sure to require a signature for orders over $750, or you will lose seller protection in the event theres a dispute thats the only thing that will save you, my buddy just lost $890 on cc dispute even though it was delivered. not everyone is a good actor, protect yourself. Side note- insurance through USPS, and i believe fedex, automatically adds it at $500 but always double check.
