There are two varieties of Mitchum deodorant for women and 1 variety of Mitchum for men that are scanning at 80p each in Tesco, although the shelf label says £1.80. (Also shows as 80p online)
The varieties are Powder Fresh and Unperfumed which on the shelf show as on offer from £2.75 to £1.80 but they definately scan through at 80p each. As does the Endurance Sport variety for men. Only those varieties though, the others are the right price.
Just got some this morning!
