Thanks for that. Apparently I will lose them if not redeemed by end of January 2010, best go up today then, will not be able to do it later. Mind you not sure how many points I have but better in my pocket as they say.
As well as instore discounts you also accumulate points on the card. They can be exchanged for a "Migros Cheque" and the value can be deducted from your shopping bill. I try to remember to redeem my points every 3 or 4 months. Any points not redeemed are wiped off of the card each year on 31st January.
