I find the same sly trickery in Tescos. Supposedly 'On offer' large size item, when you could buy 2 small-size ones making the same weight for LESS! You have to have your wits about you. I take a calculator with me, I don't trust anybody these days! The point is that many of us (the majority I'd say) are on a very tight budget. These dishonest chicaneries are just plain greedy and wicked.
