I have never seen a coupon for Driscoll's Berries (the best berries, in my opinion) so I would highly advise you to print these NOW.
Go here to register with Driscoll's
Print (2) coupons for 50 cents off any package of Driscoll's Raspberries, Blackberries, Blueberries or Strawberries. Coupon is valid until 04/30/10.
PS - My target price for strawberries is $2.00/lb so at a store that doubles I would only pay a $1 - Wahoo!
