I received an e-mail from M-Plus with great savings opportunities at Migros. Unfortunately, I can't find any information about M-Plus on a *.migros.ch page to check the confidentiality. Immediately after registering, you have to pull out your credit card for the subscription (first month free)... Migros or phishing? https://www.m-plus.ch/ <<< the colours/logo etc. are also slightly different from the familiar reference from IT: *.m-plus.migros.ch would be more trustworthy... Anyone can say that... Incidentally, the domain is not with "Migros-Genossenschafts-Bund" like Migros.ch but with a private domain holder in Bern - suspicious!
