I just had the same problem and I get through loads of coconut milk. I threw more than half in a blender with a pkg of frozen strawberries a banana and vanilla, put in popsicle containers and froze.....yum. I also use it to make yogurt. If I am not making one of the bigger things then I tend to just use the cans.

Now 95lbs and holding.
Primal, minus eggs, dairy and a myriad of other allergens.
I use this brand and store it in the fridge in a separate container with a wide enough opening to fit a spoon in so I can stir it up just before use. I would say that it lasts a bit longer the 2 days in the fridge, maybe 3-5 days. I use it fairly often in my morning iced americano (just add the milk and mix prior to ice), we use it as a cooking oil (in the frying pan with veg, or in a dish for slow cooking meats), mix it in with your ground meat for moist burgers, use it as a milk sub for a primal version of cereal (it actually has a consistency more like yogurt once in the fridge for a day so that's kind of nice).
If it gets too thick for you in the fridge, just spoon some out into a glass or something and mix with a bit of water until it is the consistency for what you want.
The Arroy-D brad is the best I have found so far since there is no other ingredients like guar gum, and it is 100% BPA free. This is very hard to find in any other coconut milk/cream product.
what to use coconut cream with?
Pretty much everything.
smoothies, curries, icecream, baking, making paleo nut ball snack things (lara bars maybe? i dont know what they actually are), put it in your bath if you're feeling decadent, whip it into coconut frosting, put it in your coffee if it floats your boat.
As for storage, once you've opened them they don't last that long. Maybe a week or two? Best bet is to freeze it if its not going to be used pretty quickly, it defrosts quickly.
If you're making a curry with coconut milk, don't boil it with the coco, because it will split. Looks ugly, tastes fine though.
Oh also, check the ingredients because some brands add thickeners and/or water.

I just cut it open and leave it open, in the tetra pack in the refrigerator. I have had no problems (it does harden...). I have left it for upwards of two weeks and no off taste

Aroy-D coconut milk (no extra ingredients) can last up to a week in the fridge in a glass bottle. I take the bottle out and pour out what I need in a second, seal and return. Don't leave the unused portion out. I usually use it up before a week though. Annoys me to plan a menu using the coconut milk and finding that it has spoiled..
For the coconut cream, we had quite the experiment occur. Knifegill bought the "Let's Do Organic" coconut cream (Let's Do Organic Creamed Coconut, 7-Ounce Boxes (Pack of 6): Amazon.com: Grocery & Gourmet Food) at our local co-op. That was at least a month, if not more ago. He heated it up enough to remove it from it's bag, and then realized he really couldn't use it like he uses coconut milk. So, he put it in a tupperware container in the fridge. It sat there for a few weeks, and then he took it out of the fridge to make space for our bone broth, and left the coconut cream on the counter, in it's container. It sat there, unopened, for another week or two (I'm pregnant and nauseous, so there's no way I'm going to investigate and clean old food containers!). Yesterday, I asked him to finally clean the coconut cream container. He opened it up, smelled it, and discerned that it still--oddly--seemed to be good. So, he put some in his eggs and scrambled it and then ate it.
It's been 24 hours and he hasn't died yet...
