When I buy ripe strawberries that are in the plastic clam shell type packaging, I look through it and remove any bruised berries. I fold a paper towel and put it on top of the berries. I flip the container over so it is upside down, and refrigerate. The berries usually last up to a week or more. The key is to keep the berries as dry as possible. This also applies to all produce.
It's kind of funny you posted this because I just did that very thing. My husband brought home a 2 lb plastic pakage of beautiful strawberries from Sam's Club. I never buy that many at once and wondered if we'd be able to use them up quick enough. Only 2 of us eat them. The key of course is refrigerating them as left out, they will mold very quickly. Also, do not wash them first. I just left in the original packaging as it had some holes but added a folded piece of paper towels. I think we may be able to eat them all before they go bad.
