PayPal gave me a US $15 coupon with a purchase of US $50 total. So, I placed an order for this
Z4 RK3368 Android 5.1 TV Box Octa Core 64Bits 2G/16G 4K Kodi XBMC H.265 US $45.50 + a
Black Mini 1080P HDMI to RCA Audio Video AV CVBS Adapter Converter For HDTV MC US $6.80 with a total of US $52.30 (Free Shipping for both). Using the US $15 of US $50 coupon from PayPal, I only paid US $37.30. If you consider the
Black Mini 1080P HDMI to RCA Audio Video AV CVBS Adapter Converter For HDTV MC is still US $6.80, then the
Z4 RK3368 Android 5.1 TV Box Octa Core 64Bits 2G/16G 4K Kodi XBMC H.265 will be US $30.50.
What I don't know is if the seller is a legitimate one, i.e. this is not a bogus offer. However, his rating seems to be pretty high, so far.
