It's always a gamble posting wine offers on here, as some people resent paying more than £4 for a bottle, but this stuff is really exceptional, and with Christmas coming up... A typical Sancerre costs £12-£14 a bottle but Tesco are doing these for £42 a case, £7 a bottle in other words. Minimum order 12 bottles. I ordered two cases and was not charged for delivery. Plus they are doing a double-up offer on vouchers at the moment, I believe.
The wife usually dislikes anything that's not Oyster Bay SB. She thought this was fantastic.
EDIT: despite what the links below indicate this deal is ONLINE ONLY.
