The package prices came from the D* website. DIRECTV: DIRECTV - NFL SUNDAY TICKET™ You are using renewal prices. Those prices are usually not available to new subs.
No, actually it's a mix. As an existing sub who did not have MLB-EI, I added it in March for $160 (early-bird, not renewal) and added SF for $40. $200 total. NFL-ST can be added (not renewed) for $269 + $99 for SF. It usually takes no more than one phone call to get SF thrown-in for free -- in this case $220 must be a renewal price.
Nobody is forced to pay it. The D* sub can choose to pay or decline.... the E* sub can only try to pick irrational fights over it.
