With the blowout deals going on with the flexi packs with the $500 voucher plus $150 for each new card registration you'll be struggling to get anywhere near that price
$1900 in vouchers for 3 BOXED NEW $600 cards. Total it up, you're getting 3 cards and $100 free if you spend $1800 on the vouchers. It's a no brainer.
hmmm....so what exactly would one get for $180?
