I know some of the wine buffs on this site will probably say only good as paint stripper but my wife certainly likes this wine so....
Mateus Rose currently on offer at Tesco for £3.26 which is £1.00 off the normal price. Buy 6 or more and their is an additional 25% off bringing the price down to £2.44 which seems pretty good to me.
This is available in store or online and is on the grocery site. It is more expensive on tesco wines
Plenty of vouchers out there as well so you might even get it a little cheaper or the voucher will at least cover the delivery.
