This is obviously a big glitch. I bought Breyers ice cream 500 ml @ Sainsburys for £2.50 (it’s already half price) went to self checkout, swipe my nectar card and this promo coupon pops up.
So I went to buy again (& again & again & again
) basically end up buying seven tubs for £2.50. Could do more but I might need to buy freezer if I do.
Worth checking this if you’re around Sainsburys, you need to swipe you nectar card to get this promo coupon.
