That's good to hear. Amazon can be wishy washy on this. I ordered some Corsair RAM from them 3-years ago and two days later the price dropped $70 dollars. Called Amazon and was told I couldn't get the new price deal.
I told them that was BS, but in the end, I couldn't get too mad as I've gotten so much money and free stuff from them (even after that), that the $70 dollars was pennies in comparison - I got two $300 dollar carbon fiber tripods from them for the price of one, because the first one they sent was an open box (tripod itself was still sealed in plastic) with the tool kit missing. They told me to keep it and sent a full replacement :)
