Already posted at 25% off but most of the wines have been put up in price. However, Sainsbury's have reduced the price of their red "Basics" wine to £2.49 per bottle AND it's included in their 25% off if you buy six or more (online and instore). This makes it £1.87 per bottle (£2.06 for white and £2.16 for rosé as this is a bit more expensive).
Excise duty and VAT on each bottle is £2.06 so Sainsburys are very kindly paying 19p to the government for each bottle you buy :-).
Let's face it, the wine is no Petrus, but it's certainly very easy to drink and has a pleasant fruity taste. Cheers!
