I used the VZWDEAL coupon for my 3-day-old Black Note 3. I do not believe there is any restriction with respect to the color you select.
Also- the Trade-in, Trade-up promotion only applies to "smartphones". The Verizon rep who took my ancient Blackberry 7950 (from the late 90's) in on trade was trying to tell me that it was not a smartphone, (I think they are looking for touchscreen phones, honestly). Since there was a folder on the phone called "apps" he was convinced otherwise. He even started saying that the trade-in has to be in demonstrable working condition (luckily I had plugged it in and it held a charge long enough to get the deal done) at which point he went and applied the $100 credit to my account. The rep I dealt with seemed to try to NOT honor the offer (at least with the device I was trading in), so I'd say that a regular phone will not get you the minimum $100 credit (but if that is all you have- it's worth a try).
Regarding the insurance that they will try to sell you- they offer you an $8/mo protection plan, and then a $10/mo plan (which is the same, with some sort of tech support added). They will NOT offer you the $5.18/mo insurance- which is exactly the same as the $8/mo insurance (according to the VZW reps that I spoke with). I assume they do not offer it since they easily sell the $8 and $10 plans all day long. If you ask them, they will tell you that there is a $5 plan (which I knew about, since I have paid for and used (once) for years.) I was tempted to ask them why they did not offer the $5 plan to me upfront, but I didn't want to push my luck. Interesting, huh?
