In my last job, my boss and I used to take it in turns to buy Copella apple juice whenever it was on special offer in Waitrose - we both loved it, but were both too mean to buy it when it wasn't on special offer.

When I'm out I'll drink Fentiman's, especially their Seville orange one, or San Pellegrino, or just ordinary fizzy water. At church it's often Shloer or sometimes a Jamaican sorrel drink which is lovely (and which you can apparently get in Sainsbury's, although I've not seen it there). But, apart from sparkling water, I'd not buy those to keep at home, I don't think.
