Rebel have reduced the Vivoactive HR to $296. That in itself isn't spectacular, but stacking it with the Westfield and Amex offers nets a cracker of a deal!
So $296 - 20% (storewide) - $20 off $50+ spend (Amex) - $25 off $100 Westfield Gift card (Amex) = $191.80 + gift card purchase fees.
That's more than 50% off from and cheaper than what I paid for my grey import about a month ago!

Edit:
Make that $171.80 if you can get the bonus $20 Westfield gift card too!

I was about to do the same thing yesterday with the Rebel 20% off offer in Melb Central but when I called up, the sales guy said that the discount applies to the RRP and not the already discounted price. Havent Seen The T&c's Of This deal so Not Sure If the same woukd apply.
If it works, could you also split the Amex amount over multiple cards to compound the cashback haha?
