This might be a trend this 2016 that those 2014 and 2015 octa-core releases might gonna down on their prices. I saw two actually, one of those is from Cherry Mobile.
Via this image and info from Teknogadyet , he spotted in Cherry Mobile's branch in SM Sta. Mesa and found out that Cherry Mobile Infinix Pure is now at Php 2,999. This is only one of the most affordable 8-core phones so far. They added a bonus with a 16 GB micro SD which is became a good deal. During my review, it has a price of Php 4,499.
Cherry Mobile Infinix Pure has Android 4.4 Kitkat, 1.4 Ghz Mediatek MT6592 octa-core processor, 5 inch IPS HD display, 8 MP rear cam with flash, 2 MP front cam, 1 GB RAM, 8 GB ROM, dual micro SIM, 3G, Bluetooth, WiFi, OTG support and 2,100 mAh non-removable battery.
The question for me right now if this offer is only exclusive at the said branch (expect an update). You can check out my review here
