I try to buy local and in season, if at all possible when it comes to fruits and veggies. You are paying $4.00 for pineapple; I live where it grows (Hawaii) and I am paying close to $3.00.
Just a little aside; When I was pregnant with my first baby, we were living in Japan and fresh fruit was almost non-existant. It was summertime and I was craving fresh fruit. I caved and bought 2 fresh nectarines at a Japanese grocery/department store. They were $15.00 a piece, US, $30.00! I must say, regardless of the rediculous cost, they were the juiciest, most delicious nectarines I ever ate :9
