I'd happily scratched BIL & SIL off the Christmas list as they have moved to HK & we won't see them, but a huuuuge parcel just arrived from them (no idea what's in it!), so it's only polite to put them back on it... They have plenty of money, have been in HK for nearly a year, & have two small daughters - I can cope with shopping for the kids. I don't know if there is anything they might be missing from the UK, I assume you can get pretty much everything there.
Any brainwaves? Cheapish, small, postable, ARGH.
