here where i live, a second hand market does not exist. it is not in the peoples culture. on the other hand you can buy a lot of food in bulk without it being prepackaged. but even that does not help because i need to put every item in a bag so it can be measured. for fruits and vegetables i can often put multiple items in one bag, but for sugar or flour that doesn't work, so no matter if i buy prepackaged or bulk, i end up with a new piece of plastic that i have to throw away.
