I have copied this from the "Selling/Buying BB thread" questions to ask, an answered them for you. Let me know if you are interested. I am flexible on price, I understand it is used. It cost me about $280 new and the extra shell cost me $90.
If you have any other questions, just ask.
1. Check the seller's feedback
I am on ebay(nb_mitch), but not a big seller(14), have 100% feedback
2. Send the seller an email requesting the following additional information:
-- Ask for the IMEI of the device
This can be seen in the picture provided
-- Ask for additional images of the device
If you would like additional pictures just ask, we I get ready to list it here,
I will take additional pictures
-- Ask if the device is brand new in unopened box or if it is used
* If the device is listed as used, ask the following:
-- Ask if the device has a Dead On Arrival refund guarantee
Never thought about it, but I would think this would involve a UPS/FedEx claim since the device is completely functional now
-- Ask if the water sensors are intact and have not been activated
Yes, not because it has ever been wet, but because I swapped the case
-- Ask if the device has an IT policy on it
No, I am a BIS user
-- Ask if the device is locked or unlocked.
* If the seller states it is unlocked, ask for a photo showing such.
UNLOCKED, photo already provided
