I was looking at the prices and noticed the 990/7125 combo is discounted more than the 970/7125 combo.
The 990 is $1099 and 7125 is $999.
Buying both seperate would be $2098, or $1898 as the combo ($200 savings).
The 970 is $699 and 7125 is $999.
Buying both seperate would be $1698, or $1598 the combo ($100 savings).
If you look at buying everything seperate, there is a $400 difference in price between $2098 and $1698.
If you look at buying the combo, there is a $300 difference in price between the $1898 and $1598.
