Now that would be a viable marketing strategy. Assuming that enough people had iPhone 6's to make a difference.
But, if enough retailers passed on said discounts to customers, then it could increase desire for the iPhone 6. As it is right now, they can't give them away. As I mentioned, on the free iPhone 6 upgrade day at my cellular provider, it was totally dead. Not so for the Motorolla's, but at this point, the only one's that they can get to take the iPhone 6 right now are the one's in the low-income program, and that's just because they don't have a choice what phone they get.
People aren't lining up for the iPhone 6 right now. Most people I know are just content with the iPhone they already have, and kinda feel "blah" about the new one. Or, if they buy a new phone, they're going Samsung or Motorolla.
I really expected to see a packed store on the free iPhone day, it's always been packed on every free phone day. But, it was dead for the iPhone 6 upgrade offer. That was the fastest I've gotten to a customer service rep in over 5 years.
And, I didn't take the new iPhone 6 either, despite it being free. I considered the bending issue, and the fact that I abuse my phones like crazy and need a tough one, and that I didn't feel like buying new protective cases.
On the plus side, my iPhone 5 is still in good shape despite getting tossed or dropped several times a day. It survives being in my pocket with boxes and such pressed against it as I move stuff, it survives getting sat on, thrown on the counter from several feet away, whatever... So, the iPhone 6 just doesn't seem like a great choice for me. And, I suspect likewise for others.
But, if Apple gave the stores a kickback, and the stores passed some on to the customers, I could see iPhone 6 use increasing. And, perhaps something might happen there. Discounts are where you'll get the customers, and that is the strength in the Target and Kroger models. And, likewise, the strength is the proposed CurrentC.
