Snowed-in survival kit

I have been searching for a 'theme' for a hamper for my mum and dad for a hwile now - and have finally come up with a snowed-in survival kit.

So far I am planning to include the following:

Two photo mugs with the kids pictures (from truprint - one free+postage, one half price+postage - total about £8 I think
Some hot chocolate or nice coffee
A retro-sweet box with some of their old favourites
A Christmassy jigsaw 1,000 piece (£1.50 from https://www.halfcost.com)
Slipper socks (from boots using advantage points)
A bottle of wine
A wheat bag (had one in the house unused anyway)
A book each (not sure what yet)
A cd or two
Candles (for potential power cuts)
A christmassy candle holder (again, from halfcost)
Maybe some nibbly stuff

Maybe a game of some sort

What does everyone think? It isn't going to be a neat little hamper, more like a box! Any other ideas welcomed!
