Close enough (that would be $US8.20) but it varies so that's the high marker. That was for iceberg lettuces, others like cos were much less, at close to normal levels or slighty more. Here, high produce prices have been almost entirely caused by repeated floods in the farming areas. More of the 'specialist' lettuces (for want of a better word) are grown hydroponically and have been less flood-affected.
(I was about to go to the shops so waited. Today at my local, one of the two big chains, icebergs were $6.90 (US4.75) and a pack of two cos $4.50 (US3.10).)
