If you activate a new line of service on Verizon, you can get a $150 Costco cash card. They already discount the phone from $199 to $177.
You may not be told about it, but if you ask, they will let you have it. We were in there talking to one salesman and overheard the other salesman discuss it with another customer. We said, "Can we get that?" and they gave it to us.
Offer is good I think on any new activation, not just for iPhones.
I believe the offer is only good on purchases/orders placed in November. My phone won't even ship for a couple weeks, but I got the order in, so they'll honor it.
