Just wanted to give an update on the Amazon transaction. I just got off the phone with them (the CS rep called me). I had already calmed down and realized that they were doing what they thought was fair, and I was pretty happy with them again, but they really made me happy today. The woman who called had arranged for a Saturday delivery for me (woohoo!!!), as well as giving me a refund to account for the current price of the TV - and that is above and beyond because they don't price match anymore. She was very, very nice.
I had already decided (and informed them before today) that this wasn't going to affect my other purchases from them, with the sole exception that I had decided not to order another TV for my parents from there. I think that they are an outstanding company, but ordering anything that requires me to be home for both delivery and return (if required) isn't a good fit for me.
Hopefully I didn't come across like a jerk to them. I fear that I did. I won't say that I'd recommend ordering a TV from them if you work on weekdays because of the potential delivery/return issues, but I still recommend them as a great place to do business.
Thanks again to all of you for supporting me and putting up with me on this.
