Quick and very good tip this Sunday: the iPhone 6s Plus 64GB silver is R $ 4,599 for R $ 4,299 at Fnac, installmentable in up to 12 installments without interest of R $ 358.25.

That's right: the 64GB model for the price of the 16GB. 😀
Only on this link, only on the silver version of the iPhone 6s Plus.
