Lot of questions from that article unanswered.

Did these people post at a red post box?

Did they post over the counter?

Did they have a fab swanky return address label or fancy packaging that draws attention to what sort of article is inside?

What suburb were these things posted at?

Yes, i saw the man reinacting his posting at the post box, and can't really of a reason anyone would steal invitations other than they just took the lot and trashed eveything they didn't want.

Surely the lady who sends a minimum of 45 parcels a day could get a pick-up, or she must have staff who could "go" to the post office in person.

She should keep an eye on ebay for for missing stock being sold by someone else.

I had 2 pairs of leather pants dissapear both small ladies one from UK one from Sydney. Over 2 months and no other mail in comming or out going vanished which I found a bit strange.
