There is only on store with a different price

We buy the Bushmens hot az hell sauce every week from spar or kwikspar and from different ones in southern suburbs and northern suburbs, and the price is always the same at any spar or kwikspar, maybe a rand or 2 difference, but the normal price is around R25, but the spar in fish hoek has blown it through the roof and made the bottle R40 a bottle, yes is might only be R15 difference, but a spar is a spar a shouldn't go so high on a product that all round should costs R25 a bottle. I just want to find out weather this is right or not.
