I keep checking my phone for updates... its only been 1 day LOL
In NC, at the bottom, there's an Edit button. Tap it to add, remove, or organize widgets.
Thank you, this was the dumb piece I couldn't quite find. I only started using NC (iOS) widgets very recently, when I got my 6+, and I just spent 15 minutes going through every possible setting screen for the Deliveries app and iOS trying to find this.

Are you on Yosemite? if so you need to add it in the right Notification area. Look towards the bottom. there is a Edit button there to add more.
Thank you, I meant the IOS widget. But I remember using the dashboard widget back when I was waiting for my first iPad, I should get that set up again too, so thank you.
I'm so used to just putting my ups/fedex/etc tracking numbers in I forgot Deliveries could do vendor-specific stuff. This is very nice, especially since the Apple Store app requires a password every time and I'm slightly nervous I may get hit with an order cancellation (I had 3 active watch orders at one point, do not now, still nervous). So compulsive reloading is happening.
