Have you tried the
Aroy-D brand? Nothing but coconut and water - no gums, which are super hard on my digestive system. For those who don't have access to fresh coconut (or reasonably-priced fresh coconut), it's fantastic.
I purchase it on Amazon, but it is also available at some of my local Asian and Indian grocery marts. The cream works out better price-wise than the milk, at least for me.
Because there are no gums, the carton contents do have to be homogenized when opened; my tool of choice is my stickblender, which fits right into the carton. After blending, it's poured into ice cube trays for portioning. The frozen cubes are stored in a bag in the freezer. Two of them go into my morning coffee as my non-dairy creamer. I typically get 21 days out of each carton that way.
Of course, some is also used for making curries, soups, smoothies, etc.
Very occasionally, a carton will have too much coconut oil. When that happens, it never will homogenize well. Best guess is that they had an off day in the production facility? Whatever the reason, it's still usable, but not as desirable for curry-making. That's only happened 5-6x since I started buying this brand about 10 years ago. But it's something to be aware of in case you are down to your last carton and planning to make a nice curry for guests. Yeah, that happened once, so I had to run to Whole Foods to get their gum-free Native Forest brand. It's not bad, but I can always taste the tin can. Blech.
