USPS question about not receiving an item but said was delivered.

[pencil1974]

So quick question here guys as I assume someone else has been through this before but its a first for me.

I bought a card ($200) off eBay and it said it was delivered at/in mailbox today. Problem was the only card delivered was one I bought off a board member (thank you Ed) that had nothing to do with the card from eBay.

I guess my question is what do I do? I sent an email to the seller stating that is said it was delivered but it wasn't delivered to me and I was going to wait until tomorrow to see maybe that it was just lost in the truck or at the post office. But do I call the post office, does the seller call the post office?

Also they didn't send with any signature confirmation which sort of baffles me at times when people don't do that on cards costing over $50, its like $3 and to me helps prove that someone has it.

So any help would be greatly appreciated.

Thanks,
Brad
