I finally got it!

It took me three times I think to understand what the cashier was saying. I had won! I had to go to the "reception" and claim my prize. For a brief moment, I thought perhaps this might be something worth claiming:) It turns out, I won a 15,000 lei coupon on cleaning products. What appears to have a high value is really only worth 50 cents. Lucky me! Now I have to figure out how to use the coupon.
