WOOLWORTHS NOT HAVING STOCK ADVERTISED

I am very disappointed with Woolworths. <br> <br> They have advertised long life milk (Woolworths brand) 6 liters for R50 in pamphlets as well as on TV last week. I went to Sammy Marks, Nina Park, Wonderpark and Kolonade, just to hear from all of them that they do not have stock.<br> <br> Why did Woolworths advertised this special if they can not provide enough stock? How will they ensure that we get stock?
