This is the cheapest K3 note I could find however delivery might take up to 60 days.
They also have Xiaomi Redmi Note 4G selling at US119.99 (US$99.99 after $20 off)
JD618 - $10 off $50
JD618X - $20 off $100
p.s. I've never purchased from JD before but as I know JD is one of the biggest online retailer in China.
p.p.s. Anyone using K3 note? Is it a good phone?
I've been searching the net for just this, and so far come up blank. There is a K50-T5 Teana version that has a ceramic speaker, and the contacts on the back of the phone behind the cover are for this, but it seems unlikely that 5 contacts are needed for a speaker, so it's possible that the others are for wireless charging and/or NFC.
So far no luck or info. I have got a universal wireless charging pad which I will try just to see if the wireless charging docks I have can supply enough power, but it's not a good solution as it permanently takes up the micro usb port and would require modifying the case to make it sit flush.
If anyone finds some info, please post it here.
