Instructions:From the email:
"As an added incentive to use our new software we are offering a 30% discount on all products for orders placed using the new 'Bonusprint Photo Service' software. This discount is available using the promotion code 'NEWSEPT08' and will be available until midnight 21st September 2008. "
NOTE: Another deal I posted gives you BOGOF on large photobooks - I'd be interested to see if this can be combined. I'll post back if it works!
