If you do keyword research regularly, then here is a coupon that you might find useful. The guys at Trellian are giving a free one month subscription to their keyword discovery tool. What is the catch? You know there is always one? You have to sign up for one moth of the keyword service and you will get the second month for free. The regular price for the monthly subscription is $59. I guess it is like getting a 50% discount of the regular price. The coupon code is “ATCH KD PROMO”. It is valid until August 31st, 2007.
