WOOLWORTHS FRUIT PUNNETT CHARGES IN QUESTION.?

Woolworths are selling a 6 punnet of Quavas & a 9 punnett of Quavas for the very same price of R45.99. This was confirmed by a manager in the store! I thought they had made an error when pricing the fruit. Same goes for the White Nectarines which are selling for R76.99 a punnet. The manager I spoke to said that Woolworths are aware of this but say that the fruit of the 6 punnett of Quavas & nectarines are larger fruit in size than the 9 punnett . This is absolutely not true as the weight of the 6 punnetts fruit -(we checked) was less than the 9 Punnett and the quavas were basically the same size as the 9 punnett in question. Being a pensioner and a regular Woolworths shopper, I check the prices carefully. This just does not seem right to me or what!!
