You can receive 5 heal kits from every facebook friends every 24 hours.
If you already received kits from a friend in the last 24h, the request has a little red cross.
no,it`s not this...i can`t receive only from this guy,from everybody else i receive easily...i don`t get it why it doesn`t work only at him
