$3 off Clorox Green Works Detergent

Become a fan of Green works on Facebook and you can print off a $3 off coupon on any Green Works natural laundry detergent (prints twice). My coupons don't expire until 7/31/2010 so I'm going to hold out for a BOGO sale! I think they are priced at $10-11 each (?). Anyone know?

While I don't consider Clorox's "Green" works products to be particularly "green" (in terms of eco-friendly or natural), this is a high-value coupon and I'm sure this detergent is still 'safer' than others on the market.
