They arrived just now!!! =D
Naturally, the delivery happened while my brother and I were out buying groceries, so whoever delivered it shoved the package in the mail box. (Thankfully, it fit, although it was tight.
0 and D have both suffered the tiniest bit in the long journey/during the mail box-shoving (-1 didn't as it was the middle one), but I don't mind, at long last I can read them
Also, the USPS tracking tool still only says "Processed through Sort Facility" and "Electronic Shipping Info Received" for my tracking number, so everyone who's still waiting: don't worry, the delivery might be less than 24 hours away.
