Sometimes I really hate Sainsbury’s

I know that when I go to Sainsbury’s they are a bit more expensive than their rivals. So what really annoys me? On a few products dotted around Sainsbury’s they advertise that the item is the same price as in Tesco. What do I infer from this piece of promotion? That everything else in the shop is more expensive!

These signs just remind me that I should buy everything else from Tesco.

Not an exemplar piece of promotion.
