As we noted yesterday the Lumia 928 is exclusive to Verizon, and is the only Lumia device with a Xenon flash:
At its heart the Lumia 928 is effectively a Verizon version of the Lumia 920 carried by AT&T. However, there are a number of important design differences, including a reduced thickness (10.7mm versus 10.1mm) and weight (185g versus 162g), a blockier casing design, and the presence of a Xenon flash on the rear of the device.
Those who purchase a Nokia Lumia 928 are also entitled to $25 of credit for the Windows Phone Store, more than enough to give you a good start on your app collection. To claim your $25 credit you will need to visit this site and fill in your details.
If you're looking for accessories for your newly purchased Nokia Lumia 928 then Amazon is a good place to start. They have various third party accessories available, including this bundle of case, screen protector, and car charger. It's also worth checking out Verizon, who are selling a number of accessories through their online store.
