I can supply Mamey seeds ($5 each) most of the year. Pulled right from the fruit just before packing (into moist media (usually cocopeat). I also ship the fruits whole (w/ seed obviously), but in the winter have to import the fruits from SA where they're often frozen (typically ruining the seeds). A lot of the time the seeds are bursting open upon opening the fruit. They're very large sometimes huge, always heavy as far as seeds go.
