Kofola Marlenka+Marlenka Kofola where to find in SK?

Hello!

I love Kofola, and I saw that there is a Marlenka variant came out+Kofola variant of Marlenka. Where can I be 100% sure that find them in stores in Komarno? I want to trip there tomorrow. In walk distance I know 2 Billa and a Lidl, or farther there is a Kaufland too, but thats double the distance.

Thanks.
