After I purchased the CD, I saw the download price for both Mac and PC matched the lower CD price (for about 12 hours), and also included a $10 Amazon gift card... would have been a great deal for anyone who purchased the download at that time. Perhaps such a deal will return.
like anything else gotta shop around. I saw Premier at retail store for $89. went to amazon $56-as you get closer to filing date you will see all kinds of price changes. Like xmas. if you want the best price shop Dec 26 :)
In other words, Amazon must compete with other sellers (Costco, Walmart, etc.) on the disk version, but they can jack the price up on the download version since these retailers do not offer that option.
