Well I have mine from Best Buy it was 55.99 and I used my $30 dollar free gift card. But my husband found one on ebay for like $10.44 and it says fast charger he ordered two. I'm sure it's coming from China and it's a different box than mine but it says Samsung fast charger on it. So I just went to ebay and searched
samsung wireless fast charging pad | eBay
Some say genuine and are cheaper but I don't know if I trust them from ebay. I had seen one on Amazon for $35. But Samsung till the 19th had buy one for $69.99 get one free but I think their out. But one said fast in the title but the charger itself didn't say fast charger on it but the ones my husband bought it says fast charger so will see when he gets them but for $10.44 can they really be a fast charger? i don't know.
