Tim Horton’s is one of Canada’s leading fast food / coffee joint chains. I saw this menu (first photo) yesterday and it is the first time I saw the price proposal combo so Highlighted.
It is a subtle nuance, but here you have the image of the beverage and the dessert in the price box, and the price box is highlighted by a square.
On the second photo (below), the image of the additional items (beverage and dessert) are not there and both price proposals are almost similar in presentation.
I found that ‘seeing’ what I lose if I chose the cheaper option instead of ‘imagining’ what I gain by paying more was very compelling.
