I've just returned from the post office and it cost me £8.96 to send the wretched make up back. It works out that my refund will be worth £16.95. That's not good enough really as I feel I should have my postage both ways refunded, but I know that's not gonna happen. It's not ideal, but I would either of had to throw it away or give it away, so it's better than nothing I guess. Lesson learnt!
