as S-group customer/member, I get periodically the reports on the astonishing amount
of money I collected through their bonus system

With the report, it regularly comes also the invitation to get one of the their new S-Etukortti.
My situation is that I have my own (bank) credit card, which I use mainly for online and bigger
purchases, and a traditional bank card (without chip), for the everyday shopping.
As S-group member, I have the old Etukortti, which entitles just to collect bonus points.
Now there comes this offer of three new Visa Etukortti cards: Debit, Credit, and Debit+Credit,
with their S-Tili account.
I don't feel a need to get another (bank) account, and I guess my bank will provide me with a debit card
when it will be needed.
What would you do, or maybe you went already through this, how did you decide about it?
Should I just keep the cards as they are now until they are valid or would it be beneficial to try one of those?
