Ordered Mar. 17, arrived today, Apr. 2.
This morning, an hour before delivery, USPS tracking still said that they'd rec'd notice that it was to be shipped, but the package hadn't been delivered to the post office yet. Now the tracking site does say "delivered".

Graveyard mall customer service wrote me last night to say that all of the orders had been shipped. So, I'd guess they should all arrive by Sat.

Oh, and thanks to the OP! Mrs. Gargoyle has been asking me to fix her broken sunglasses for a week, and I kept putting her off...
