Well, I don't know if they're available in stores now, but the last time we checked, they were $2 to $4 a piece, which is pretty much the same as unavailable to us! So this box is worth a fortune, not to mention the love and care of the one who sent it to us!
It is so weird, I have been trying to find passion fruits recently, without success, when I lived in England we could get them all the time, I miss them! Send some my way please..... ;)
