Reusable breastmilk storage?

I really want to breast feed this baby she's my second and I feel like I didn't try hard enough with my first daughter however the storage bags seem really pricey 12 for just 100 doesn't seem worth it to me cuz its essentially a small ziplock. So I was wondering if there's a cheap reusable solution or maybe if I can reuse the bags? I've been looking at like glass or even plastic ones but the glass ones keep mentioning expanding when u freeze them. And possibly exploding and the plastic ones at least the ones I've found say something similar plus I live in an apartment and have a small freezer I don't have much storage space. Any tips would be greatly appreciated that in advance no mean comments pls
