Woolies has the Waterdrop Electrolyte Drink Cubes Berry 12-pack down to $8.50, slashed from the usual $19.00, so you're pocketing $10.50 right there. Each little cube dissolves in water and delivers electrolytes plus vitamins with zero sugar, which makes them a solid pick for school lunch bottles, after-sport recovery, or just staying on top of hydration through a hot week. At around 71 cents a serve they're genuinely good value compared to sports drinks you'd grab off the shelf at twice the price. Grab a couple of packs while the half-price deal holds.
