I just used the online grocery delivery service from www.leshop.ch and it was great. The site is totally easy to use, with English instructions, and there is a good selection to choose from - including many international items.

It's connected with Migros so you can collect "M-Cumulus" points too. The delivery fee can be as low as under 8 CHF. Plus you don't even have to be home when they deliver!

If you try it out, you can enter my email as a referral and then you'll get 10 CHF discount on EACH of your first 5 orders (so you save 50 CHF total). It's: ecombg at gmail.com (using the @ of course)

Enjoy!
