Filtered milk.

I only buy milk with my weekly shop (no local deliveries) and discovered filtered milk recently. I can reply on the milk not going off and don’t have to throw the last few inches away. It only seems to come in 2 litre bottles so I decant it into 1 litre ones which are easier to manage,

I always use filtered milk now, generally get the skimmed one in a litre bottle. It lasts much longer, which is handy, as I am on my own and don't use a lot.

We don't use it. We go to a shop that sells milk from a self service machine, you take your own bottles along and just refill. We are lucky that we live near the shop and go there every three days of so. So no plastic.
