My aunt is in assisted living and no one lives in her house is empty. I am selling numerous items on Ebay for her and used to drag items to my house in order to take pictures and do the listings. I recently took a desktop to her house and plan to do everything from her house. I need to find the cheapest internet service options available. At my house, I have to use a private wifi company since nothing else if available so I don't know anything about Cox, ATT, etc. The internet at her house is not for gaming, watching movies or downloading music. It is ONLY to access ebay. What is the cheapest option I have?
