If you have bank account at Raffeisen did you applied and payed for Membership? Do you find the MemberPlus-Status reasonable? Do you use its benefits?
Every branch probably has different conditions for the Member Plus membership. In our case, we had to buy a share from the bank, which we can sell when we no longer wish to be members. It's not generally something you automatically get.
The membership is great! Many discounts and free things. Ski ticket discounts, free access to museums, etc.. We use it all the time.
