****** during sale

During Shoprite's big red sale I tried to buy nappies. They kept telling me its out of stock and when black people ask for nappies they get from the storeroom. I had to ask a black person to ask for nappies, he did and I got my nappies. This is ****** and unacceptable! They also allowed black people to buy 6-8 packs of nappies and only allowed us to take 2 ( the special is 2 packs per person). I am shocked and furious!
