Even if you are driving, a one month Half Card could be interesting - 50% off buses, trains, cable cars and some boats. It is 100 GBP and will make itself back with a return up and down the Jungfraujoch or the train into Zermatt and cable car up to Kleine Matterhorn.
You buy bin bags from supermarkets in a lot of places and the cost of rubbish disposal is linked into them. Get good at reducing the size of your litter and squeezing it into public bins which are seemingly designed to stop you doing that.
As was said in the above post - get an overdraft! If something comes from Switzerland it tends to be on a par for the price with the UK if bought in a supermarket - bread, local veggies, beer. If not, prepare to be amazed. Packet of crisps for 4 quid was my favourite. If there are any huts still open I think some of them work out cheaper than actually existing in the valleys. I heard the minimum wage is over 20 quid an hour so locals can absorb this.
The climbing around Basel is really good and hardly visited by Brits. Had some good campsites. I did go in 2004 though so can't remember specifics.
