RE: "possible very expensive claims"

I think that if you claim you are ethically sourced and high quality, you need to back it up, and that can be expensive. E.G. trips to farms, process to check on them, constant quality control etc... But if you are upfront and just say "this is a random coffee we slapped a funny sticker on lol" then, you could do without all those--but the price should reflect that.
