How about gust giving her the 25 quid? When I was that age, unless someone was offering to buy me a stereo or something else in the "impossible to even dream about saving pocket money for", I always preferred cash to "stuff". My gran was a big believer in giving money instead of things, as it let the recipient choose what they really wanted. After all, she might prefer an MP3 player or Sisters (or Cybercide!) CD to clothes or bags.
