Disappointed in Information Sharing

I recently purchase a Trojan TR510 Treadmill from Game for R9,999, only to find this product being advertised a few days later for R6,999 at Makro. When shopping around for this, I had enquired at both Makro Springfield and Game (Pavillion) on any upcoming specials and was told no. I am sad that I had to pay R3,000 more for something I could have got a lot cheaper if I was aware on the imminent price change.
