does anyone know where can I get plaga wine in 3L boxes under 400k around kuta-kerobokan? thanks
You can get Plaga red or white at 'Tip Top' in Kalibukbuk (in Lovina in Nth Bali) for 380K each. (I know you said Kuta-Kerobokan which is in the south.)
But, serious drinking follows.
If you have a bud coming to the north they can go to Tip Top which is on the main jalan next to the Chonos Hotel, in 'Lovina'.
There is also ALCOVINA in Kaliasem (nearby to Tip Top and the mosque) who would probably do a delivery deal but I think they charge around 395K a box retail. Plus their delivery charges.
Maybe keep hunting around down there in the South. Everything seems to cost more in the South of Bali.
Best luck.
