coupon code will only work if clicked from my link.
on the right of special offer, click on "create your bundle and save....." and add Canon 600EX-RT Flash for $5.79. Add Main bundle to cart and add flash on the next confirmation screen.
in cart, apply coupon code SD1104ADS
for $300 discount - $350 rebate [adorama.com]
= $1404.79 + free shipping
btw, they list 600ex flash but I believe it's 2nd gen model, because few ppl grabbed similar bundle last time and all got II's instead of 1st. i dont even think they make 1st gen anymore and it's likely a glitch on their end.
