Is this possible?
I've chosen Royal Mail but the only option available for me (as I have chosen RM as my only postage) is 2nd class small parcel and Vinted have set the cost at £3.49
This is far too expensive for the small item which could be sent as a large letter, or maybe an ordinary letter.
Their Help page says look for 'Custom' when setting postage/ delivery but it's not showing.
Any ideas?
