Thanks for the idea about the chat. I had ordered a kindle case and did not get the promotion. I pointed it that it said it wouldn't work on kindle devices but said nothing about accessories. They applied the credit. Yay!!!!
According to Staples, they have the Kindle Fire HD without special offers. That makes it $15 cheaper than Amazon, plus the $20 rebate. I went in and got 2 today for Christmas presents and will use the rebate to get covers.
I got a Duracell 15-minute charger from Wal-Mart for $27 and it came with 4 AA's, but also charges AAA. It also charged my Rayovac batteries in the 15 minutes. It's well worth the money for the quick charge.
