I don't remember where I saw this or heard this, But Lorie and I think it's brilliant... We don't have these problems, anything never disappears from our front step... Could sit there for weeks. Anyways what we saw was this guy taking his Amazon box, downstairs, filling it with dirty cat litter, taping it back up... and then putting it out on his front steps, so the Amazon Pirate jumps in and steals it... Guess he does this every few months... Just an idea... if anyone has problems with these pirates...
