We didn't have Majik Market where I live. I also don't remember Star Wars cups, except as glasses from Burger King(?)
There were a ton of Marvel and DC superhero cups, though. My comic store still has the old ones for sale.
However, the consistency of the drink in that ad looks more like a Slurpee/Icee than the rougher looking slushy. Both Icee and Slurpee are the same IIRC.
