What would you do?

Hi guys,

I received two orders on Friday for two items within 10 minutes of each other from two different eBay ID's, however, the address is exactly the same address. Thinking this may have been an error or the person ordered two of a very similar item (perhaps siblings buying for a gift) I messaged the buyer both through eBay and when I did not receive a reply through the mobile number provided. I have still yet to hear back. The items are both for around $1500 each which to me is a lot of money. 

 

Would you send anyway or does this sound a little suss? All opinions gratefully appreciated.
