I assumed that the Cumulus data would be used to analyze my shopping behavior and that I would receive vouchers tailored to me (yes, the vouchers are different, my parents receive different ones). I shop regularly at Le Shop / Migros Online. I was therefore initially delighted to receive a 25.00 voucher. But what should I do with a voucher that is only valid for first-time customers? Should I create a new account for every order?
