This is an outstanding deal for a premium running shoe. Plus you can get an extra 2.8% cashback with Cashrewards.
Rebel Sport has it listed for $259 minus 20% at the moment and $20 AMEX cashback ($188).
It appears that there is at least 59% off all the Mizuno running shoes: http://www.wiggle.com.au/running-shoes/?ea=4294789512
I originally read this as (Mizuno sneakers) "3 for $103.99". Was about to go nuts. Then reality hit… :(
