Marry that with the site is supported by volunteers that have far better things to do than referee why you think paying £15 for a seal because it's grey should leave you with feelings of everlasting happiness over the black ones but it didn't. I'd nominate checking the credentials of any 3rd party thoroughly before engagement and have some knowledge on consumer rights.
