Unexpected value

I recently received a flyer from these guys for various Samsung products. The timing was prefect as I needed to buy a new washing machine and microwave. As any sensible person would do, I compared prices with other on-line retailers. The washing machine was about R 500 less than any one else so I decided to buy it. BUT, here is the reason why I write this. Upon checkout, unexpectedly, I got a further R 1600 discount. Including delivery, I paid over R 2000 less than the nearest competing supplier, the microwave purchase was similar.
