the samsung wireless charger is $20 buck on amazon..Verizon would have given you $100 for ported number + atleast another 100 for your old smartphone (If it works)
Actually, the new Samsung wireless charger that came out with the S6 is closer to $50 (though, yes, there are other less expensive options on Amazon for wireless chargers). The Verizon $100 port-in offer was only if you wanted to go on the Edge program (I didn't), and my old M8 should sell for considerably more than $100 on ebay or swappa. All that, plus I was able pre-order several days earlier on BestBuy before Verizon opened pre-orders.
