This. Keeping it in a dark, cool place should suffice but for longer term storage keeping them chilled (or even frozen) is better. Additionally, it slows the image degradation after you've exposed the film (but haven't developed it). Film is very robust (see Vivian Maier's undeveloped rolls from the 50's/60's, Garry Winogrand's from the 80's), but it's good practice to keep everything as fresh as possible. Plus seeing a wall of film when you open your fridge is just awesome imo. I have about 90 rolls in total at the moment, at my current rate I'll be done with them by the time August rolls around.
The expiry dates on the boxes are 2017/2018/2019 (fresh batches from Ilford) so I have time.
