I saw this today and thought I'd grab a few. It's only for the Orange and Ginger flavour which is apparently an end of line flavour so they are clearing them out. I assume it's while stocks last. I'm not sure how many more they have. It might be worth checking other stores to see if they have this deal.
I was hesitant about the flavour but it is actually quite nice.
Didn't even know Rekorderlig did that flavour - never seen it anyway. Just checked the closest LiqourLand to me and nadda. :(
