I'll chime in on this.
No, there hasn't been much of a holiday for me. An insane amount of orders have been pouring in, which I appreciate, but it's also slowed me down a bit. What used to be 10+ orders a day, has turned into 30+ order a day, which makes a huge difference.
What used to take me hours to turn around, pack and ship, as my business has more than doubled, so has the amount of time that it takes me to get things done. I am cranking them out as fast as I can.
USPS Priority Mail Tracking Numbers
These have to be the most worthless things on the planet. They serve as little more than notification that you have something that's been processed on your behalf. Because USPS rarely EVER updates their database to reflect accurate information.
BUT, if you did get tracking info, at least you know, something is on the way out the door.
