DS (16) is going to Australia for 2 weeks with his best friend and their family. They are staying with his best friends auntie and my Mum suggested today that we should get a gift from DS to say thank you for having him. I think it's a great idea but I haven't got a clue what we could send - it would have to be reasonably small and fit easily in a suitcase full of clothes. I'm thinking around £10-£20 budget. I don't know these people so would have no idea what on earth to buy!! Yikes!!!! 
I only have a couple of days - can't believe this hasn't crossed my mind before! Therefore am posting in AIBU as I know it will get a quick response!
TIA
