Just sold $1k item to a new buyer with 0 feedback, should I go through with transaction?

Just sold an item ($1k value) to a newly created buyer account. The buyer has paid for the item and shipping address details look fine.

Should I be wary of this transaction or am I just being paranoid and just ship the item.

Ship the item. At that cost you will have all you ducks in a row. Like tracked shipping, SOD, insurance...

You must send it tracked with Signature on Delivery as it is over $750.

Insurance is a necessity.

Postage will cost a bomb due to the size of package though.

If your spider senses are tingling, you have the right to cancel.
