Long story short, went to Bing Lee today to buy a new 4K TV ($1850) and was planning on pay with Amex to take advantage of the spend $300 get $50 back offer.
I actually have 6 registered Amex under my name and my wife's name, so I said I wanted to split the payment in 6 cards (in order to get $300 back). The saleswoman was a bit shocked and went straight to the manager to check if hey could do it, but came back and said they wouldn't allow because it was suspicious (WTF?) as they've had some incidents in the past.
I walked out of the shop in anger but in hindsight I should have asked to speak to the manager as this doesn't make any sense to me.
Question: Do they have the right to refuse this kind of transaction?
Why not just wait for the next 20% of sale, and pick up said tv from goodguys?
