Re: samsung $200 trade in promotion
I just checked Samsung's $200 rebate website and they require you to trade in your existing phone prior to receiving your Note 4. If the phone you're trading is the one you're currently using that doesn't make any sense.
I think you are mistaken.
https://samsunggalaxypromotions.com/Note4/ is the web page that lists the steps:
1. Preorder the GN4 between 9/19 and 10/16
2. Trade in any working smartphone (tiny print at the bottom says it must be worth at least $10)
3. Starting 10/10, come back to this site and submit your
purchase and trade-in information.
4. Enter your contact info.
5. Enter your device's HEX MEID (which means you've got to have purchased and received your new phone)
6. Upload both preorder and trade-in receipts for validation.
The tiny print at the bottom says that your return to the Samsung page and submission of claims (as described above) must be done between 10/10 and 11/30, which extends roughly six weeks after the deadline for preorder of 10/10. Given all of that, it looks to me like you can pre-order the GN4, then when it comes in you go to get it and trade in an old smartphone, and then you go back to the Samsung web page to submit the pre-order and trade-in receipts and purchase info for your new GN4.
