Missing shipment

If USPS shows that the package was delivered to you, you will have a hard time proving that you did not receive it. If it was insured you would still have to prove that it was not delivered to you. Next time you should request a signature conformation. Hopefully it will show up ,if it doesn't you're SOL!

That’s why USPS is only good for insured or certified mail. I’m sorry to say you’re probably SOL. The burden of proof will likely be on you, but try contacting your local postmaster. Who knows..maybe they have an employee who they’ve been suspecting of theft. It happens in that organization.

All someone has to do is wait to see if you're home and then walk up and take the package. Happens all the time in the land of the free. Like stated, unless you're required to sign for it, there's not much you can do.

Check with you neighbors to see if they saw something or someone suspicious loitering about and if they themselves had any problems recently. Police will tell you it's very likely someone who lives close by (within a two block radius) so you might be one of many who've been burgled lately. 

If you're lucky, the idiot will strike again and be caught and hopefully, you and anyone else can inquire and look to see if he has your gear.

All the best,

If an item is insured for at least $200 with USPS, then it will automatically require a signature.

"We did not discuss insurance. I assumed that he would do so since $860 is a significant sum."

Even if the other person was a good friend, I would never assume anything. These days it's best to make sure every "i" is dotted and every "t" is crossed.

I would never have something delivered when no one was home. Ship to work or have it held at the shipper for pick up.
