iPhone 6+ is still more sought after than iPhone 6. Walk around TPY central, many dealers still take in the 6+.
Apple + new phablet size = commodity
With more positive reviews that come up over the following weeks (especially over practical usage parameters like better batt life), you can expect demand to maintain or even increase. Furthermore, many peeps view the iPhone 6+ as an iPhone and iPad Mini all rolled into one. I'm pretty sure many are ditching their tablets after getting the iPhone 6+, and many ex-apple users who had transited to Note 1/2/3 and other Android phablets due to the bigger screens will want to transit back due to the bigger screen AND useability that IOS offers.
Another trend that takes similarity to the release last year...
Demand for 6+ is akin to that of the 5S
Demand for 6 is akin to that of the 5C (though of course NOT as bad as the 5C)
At the very very worst case, I'm pretty sure u'll still be assured of a couple of hundred of dollars margin 3 weeks later when you flip the phones, albeit a lower margin. But who knows, some TPY dealers I'd spoken to today claim resale prices may even creep up once the current global batch is lapped up.
Bottomline, a few hundred dollars margin is still better than nothing right?
PS: And kudos to you for being honest about flipping the phones for profit
