Ok probably not a preppers post as such but I thought you would be the best people to ask 
Following the last lockdown, I have found that buying ‘ big quantities was probably better than supermarket shop for a lot items.
Eg we’ve started buying flour in 15kg bags. We make all our bread (1 500g loaf a day) so it goes quickly. The flour is better quality and cheaper than supermarket stuff.
I’d like to do that for other products (coconut milk comes to mind because I find it hard to find a brand that is of good quality), canned tomatoes (we seem to using a lot of it) etc....
Same with spices (the plan would be to buy them with a couple of family members and share).
My question is: do you know of any good websites where you can buy in bulk like this?
