Black Friday at Makro.

I have been wanting to purchase a 3D printer and thought that Black Friday would be the perfect opportunity. I reviewed the different models and once decided on I went to Makro Alberton to make the purchase. The particular model I wanted was now at a higher price than it was advertised normally at. I questioned the staff and they said its head office who sets the prices. Someone eventually agreed that I could have a R 500 discount. I agreed and was then told there was no stock but I should come back the following day and it would be sorted. I subsequently went back only to be told they could not get that model I should order on line. I returned home and went online and while preparing to make the purchase noticed that a better model which I had seen on the shelf was being advertised at a R 4500 discount. I went back to Makro and was told that model to was out of stock. I showed the salesman the one I was reffering to which had been pushed under the lower shelf and then the problem was the price. They were not aware of the discount. I made the purchase and took the unit home only to find that it is faulty, although the box had not yet been opened. All in all not a very frustrating experiance.
