So about three litres for the price of a can of Red Bull.
Its only the one with sugar they stock & the bottles lack the yummy sounding glucuronolactone they have in the cans.
If the price is not showing in the shop, as they to "swipe the card" for the deal, as they have a card with the offer barcode in a book under the till.
