There's someone worse with numbers than I am

Numbers aren't my strong suit but the prices below don't seem to add up.



Seems smarter to pick up a 400ml bottle of lemon scented Palmolive dishwashing liquid from the left and save $1.75 rather than the same bottle from the right side to save only $1.

 

Perhaps Coles should reconsider stickering their specials during the wee hours of the morning when their staff are perhaps not wide awake?
