If i order a phone off amazon wireless, do i still get the accessories if i was to order off sprint?

I have sprint, and i have the $150 upgrade thing, im on a family account, and will be upgrading into an extension for 2 more years. My question though, is if i order the phone i want on amazon its 20 bucks cheaper, but will i get all the accessories like the SD card, the charger, etc?
