I found alloy rims very expensive in Switzerland and anyway couldn't find ones I liked.
Being a bit mean, I searched around for days (possibly weeks) before finding an online shop in the UK that delivered free in Switzerland and the prices were much better

. The free delivery made all the difference, other firms wanted more than the value of the rims to deliver.
I needed big ones so it may not be the same advantage for more ordinary sized wheels and you must be aware you will pay import duty and MwsT at 7.6% (but you won't pay the 17.5% VAT in the UK).
For what it's worth, here's the
website.
