Freixenet Ice Cava 75cl offer price £7.50 reduced from £12 when you order by 14/02/2017. Offer subject to availability. Maximum 20 promotional items per customer.
£12 in Tesco £9.00 in Ocado so seems a good buy and although there are only a few customer reviews they seem positive so might be worth trying.
Also Freixenet Excelencia Rosado Vintage Brut Cava 75cl £6.50 instead of £9 also in Morrisons.
