Can anyone confirm where to buy the Samsung Charger for the Verizon $50 rebate? My local Verizon corporate store doesn't stock them, then said that they weren't eligible - go to an authorized retailer. So I went to Z-Wireless, they don't stock them either, and said that I should go to a corporate store. I said they sent me to Z-Wireless, then they sent me to Best Buy. Bought one at Best Buy, submitted receipt, and Samsung said "Your purchase did not occur at a participating Verizon retail location". So returned it to Best Buy. Has anyone successfully submitted the rebate, and where did you purchase the charger?
