Often bundling ends up being cheaper than buying services separately. I do, and they even gave me a landline, which I never use, but it still saved money. Regarding your summer residence, depending on the carrier, we have "stop-n-start" service. You pay only for the months/weeks/ days you are there. They will turn it on when you arrive and off when you leave. During the months we are gone, there is a $10 maintenance fee to keep the account open, but it saves paying for services on an empty household.
