eh.. i've not ever had UPS lose my package. I imagine amazon would take care of the situation for me real fast if UPS lost it.
And I don't choose downgrade option so I'm good. Amazon already has my credit card info (amazon card) so what's the difference.
Guess I just see there being a big difference -- and it has nothing to do with selecting 'downgrade option' (which I never use either). If Noram loses your item after it's been delivered (sometimes they'll misplace it and it'll just say "Processing"), or UPS doesn't deliver it, it's now money coming out your pocket and your credit card being charged. Amazon might still take care of you, sure, but you're going to be haggling to get your actual money refunded instead of just not having a credit applied. Personally that's a big difference to me. I'd rather not start a process of being charged for trade-ins they botch, but YMMV.
Also, Amazon isn't going to take care of the situation "real fast" if UPS lost the package. I just had a trade on 2/4 sent to Kentucky. It tracked every step of the way but on the last leg got stuck on "Out for Delivery" and apparently never got there. The Amazon rep says I'll get my credit applied but not until 30 days has elapsed from the time of shipment, so I have to wait until 3/4 for something I sent a month ago.
Sounds like you haven't had a bad experience with the trade-ins. Make enough of them and, at some point, one of these things is going to happen to you eventually either with Noram losing an item, or not crediting you, or not returning the items they rejected (that's also happened to me), or UPS losing the package. You'll probably have a different viewpoint about getting your CC involved then
