Where I am at, 8+ will retail at 1150 USD, but there are usual cash back offers from credit card companies to the tune of 160 USD. (all nos. inclusive of taxes). I would have loved 7+, but no cash-back offers there, and it will end up costing just 50 USD cheaper, with lesser storage.
My ideal phone would be iphone 8 with dual cameras. But after having owned a 6 for a while now, I really envy the 7+ camera capabilities.
On a separate note - Right now, iphone 8+ is near about the same price point as galaxy S8+. So I think iphone 8+ is priced well. I honestly don't get why x had to be priced so high. Just because of the display?
Not sure what the 'RRP' is for the S8+ but I've seen them here in the UK now for about £620.. iPhone 8+ starts at £799...
