Cost effective ways of storing breastmilk for daycare?

I also used trays.. Qubies they are called. Each cube equals 30mls so super easy to measure out portions. Once the tray was frozen, I'd pop them out into a larger container and store in the freezer. Super easy to pop a few cubes into a bag or bottle to take out and much cheaper than using the bags all the time.

I haven't stored milk for a long time, (starting again soon!) but I used to freeze in ice cube trays and then pop out into dated snap lock bags. I'd then take out the required number of cubes for a feed when needed.
