For those of you who are having trouble tracking your shipments from Crazy On Digital even though they gave you a USPS tracking number, email them and ask them for the proper site to track your shipment from using the tracking number provided. I recently ordered the accessory bundle for the Note 10.1 2014 (it incudes the screen protector) from them on 10/18 and the tracking number they gave me never worked on the USPS website. I emailed them and they sent me the correct site for tracking.... DHL picks up the package and once it hits your state, they hand it off to USPS, and it gets a 2nd tracking number (it will be on the DHL site on the right-hand side of the tracking page). That new number took me to the USPS site and it gave me tracking information after about a day. So if you have a USPS tracking number that isn't working after the first day or two, email COD and ask for the proper tracking page, or try using DHL.com for tracking.
Hope this helps.
