Has anyone upgraded programming this way?

Has anyone upgraded their programming through the web or via the reciever and it come up correct on the bill?

I currently have the HD Gold package but seriously considering upgrading to get all the movie channels.

I dont want to have a pricing fiasco on my hands and hoping if I did it through the receiver or web all the pricing is automatically calculated via their computers.

After going through all the hell with standard customer service overseas I was hoping doing it electronically would eliminate those issues.

Has anyone tried this?

did you get all the discounts if any?

Im thinking on either doing 2 for 20 or just getting all 4 movie packs but want to make sure it shoes up correctly on my bill.
