Refund of the difference between price paid and price on special

Two weeks back, I bought an HP printer at Makro Springfield Park and paid R2.499. The following week I was in Makro again and saw the printer was on special for R1.999. I mentioned my bad timing to the salesman and he told me that it was Makro policy to refund the difference if there was less than 7 days between the date of purchase and the date the item went on special. I had bought the printer 9 days earlier but the salesman said I should try for the refund nevertheless. I gave my details at the refunds counter and was told they would have to check with the department manager who was in a meeting at that time and they would phone me with his decision. I received a phone call later that afternoon saying that in the interests of good customer relations, the manager had authorised the refund even though I was out of the policy time limits. I went to the store the following day and received the R500 refund. My thanks go to the salesman who informed me of the policy, to the very helpful staff in the refunds department, the department manager for his generous extension of the time allowed, and to Makro for having such a policy in the first instance.
