November 29th. You're correct - and that was my original plan (as I noted earlier), but the rep on the phone was actually really helpful and we didn't even bother talking about going into the store and running with the restocking fee. Now, I've been a Verizon Wireless customer for 11 years, and he did note this a few times on the call, so that "loyalty" may have come into play when he was putting me on hold and confirming what he'd be able to do - or not do - for me.
Having said that, it's safe to say that anyone that purchased the Rezound between 11/15 and 12/28 should have until Monday to get at least $65/credit.
Also, do make sure that if you bought the phone, originally, with a "new every 2" $50 discount, that should also be applied to the "new" $199 purchase price (so you should only expect to pay $149).
