Storing breast milk

I will be breastfeeding, and may sometimes need to pump. I have the evenflo double electric breast pump so I would like the storage to be compatible with that. I saw that Phillips has storage containers that are compatible with its own pump. I really like the idea of re usable containers rather than buying bags and throwing them out all the time. I am a first time mom and know nothing about breastfeeding and storing breastmilk. What would you all recommend?
