I got a savings card when I was 18. I connected the Thank You program to the card and collect the refund in points immediately, without waiting for the end of the month, which I can exchange for money. . In general, I have only positive impressions of the Savings Card.
I looked in on my own business, I didn't notice any queues, and after 5 minutes I already left with the problem solved. The whole process was quick and enjoyable.
