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?
Hope you can receive it soon. Looks like the tracking system is useless, cannot see any location/tracking.
