I don't know why she hasn't posted she received yet dotty. But, the post office tracking says it was delivered October 31.
"Your item was delivered in or at the mailbox at 9:39 am on October 31, 2015" I omitted the address so people could not see it here.
Some people will not know who you are until the day of the party, because the card inside will show who you are on the board ladies. But, if your package is showings delivered at the USPS tracking number Site on line, it is a pretty good indication that they have the package.
