Jogged over to Mrs D and she had two parcels for me to post with the most beautifully written instructions I've seen (someone was paying attention in school!).

The Post Office queue was massive but luckily the sky was blue. After 25 minutes, it was my turn to return a parcel and send another.

Mrs D was super happy and is so very grateful to all the GoodGymmers who have come before me to help her out.
