When we Tidings from here because we had not heard from them even after almost a day had passed from the scheduled shipping date, they told us that they had sent the package yesterday but forgot to stamp the shipping notice along with the shipping notice. As a result, the postmark was 3 days after the date it was sent (or so I was told).
Purchased on 10/7. The actual postmark was 10/17 (Mon.), which was a big difference, and it took 13 days from purchase to arrival without any Tidings of shipping delay.
