Yep, one of those deals where it's cheaper to buy two than one. Don't know if anyone actually need that many mustard, but if it's a deal..
Colman's Mild English Mustard 155ml £1.09 each or 2 for £1
Colman's Dijon Mustard 150ml £1.19 each or 2 for £1
Colman's Sweet Hot Honey Mustard 155ml £1.19 each or 2 for £1
Colman's Hot Chili Wholegrain Mustard 155ml £1.19 each or 2 for £1 (for reasons unknown not online)
They also had Colman's Wholegrain Mustard 150ml for £0.95 each or 2 for £1 - if you feel like splurging a bit.
Deal expires 16 Dec 08. Link is to Tesco website. Added voucher but no idea if it works or not. As usual mod pls put pic I don't know how.
