On that site, you should be able to list different products and alternative ways of making those products yourself. For example, take a deodorant, toothpaste or body oils. There is no need to buy these products. It’s super simple to make. It’s healthier and cheaper. Hence, on this site people should be able to share different receipts on how to make products. And, you should be able to vote on the receipts, so the best ones are highlighted. Of course, this solution should be on the dWeb, like IPFS.
